Who cares what is easier?  With calculators, both handheld and online, nobody does any actual math any more anyway, so it doesn't make any difference what numbers they use.  When entering scores, you enter either the total score or hole by hole score and the program or website does the figuring.  Same for  course handicap.  Much ado about nothing.

Lot's of truth here but to me it is harder to remember that 113 is the base.  i.e, if I didn't play golf for 10 years, I would probably have to look this up again, but if it was 100, I likely wouldn't forget it.  It is good to know generally what your handicap should be on a course without the use of a calculator as people can make mistakes with them.

I grew up with inches, yards and miles, but you have to admit that metric makes more sense and is easier to learn for someone who is not familiar with either system.  I would bet there are lots more Europeans who could tell you how many meters there are in 1.6 kilometers than Americans who could tell you how many yards there are in a mile- even with the use of a calculator.

If person knows his exact handicap and cares about it, I would imagine him knowing how to compute playing handicap. On another note, here we have in the club houses and at the first tee a sheet where you can quickly find out your playing handicap. So you do not have to calculate anything if you do not want to. Also on every golf course web page they have HC calculator where you enter your exact HC and out comes playing HC for each tee and gender. Easy peasy. And we use slope+CR, not just slope to calculate playing HC, how complex is that?!

It is easy peasy for me to calculate also, but I am really good at math.

I have played at courses that have a index chart to CH chart posted for each set of tees, BUT one of the ones I play at currently only has a single ipad available to look up your CH if you don't know it.  For men's league, this course simply rounds index to get everyone's "handicap"  This worked fine last season when everyone was playing the 113 slope blue tees, but this year the have the low index players off the 117 gold, the middle guys off the 113 blue and the high index guys off the 103 whites.  I have tried to convince them that they need to 1, calculate everyone's CH using slope and 2, adjust for the 2-4 stroke CR difference between tees, but this has fallen on deaf ears so far.  This results in the guys on the whites getting a 5-7 stroke HC advantage from where they should be.

To be fair, the guy who took over running the league a week or two before I joined has said that he would consider it for next season, but thought it would be to hard to change mid-season...apparently not so easy peasy for everyone.

You don't see too many 74.2/105 courses.

This is just conjecture piled on top of what is quite literally a pointless discussion. I'm still done.

I was hoping to get a simple answer when I started the thread, but nobody came up with one that seemed correct- most seemed like conjecture to me.  I will admit that my thought there was a "grand scheme to obscure and confuse golfers" (your words) is also conjecture.  the real answer could be that it didn't occur to the originators how easy it would be to have the "average" be 100 instead of 113.  Alternatively, maybe they based it on some existing system or ....

I think that it's a European plot.  Since kilometers are a smaller unit of measure, and since European countries are all fairly small, by using metric it sounds like the distances are greater and therefore the country seems bigger.   Instead of only 100 miles from here to there, it's a whopping 161 km.

The Pope of Slope website gives an explanation of how 113 is derived from a different point of view compared to the USGA site.  It says that the average slope is 1.13 which is multiplied by 100 to make it a round number.  My thinking is that they could have multiplied all slopes by 88.5 (or 88.49558) to make it a round number with the average being 100.

3. Slope Rating

The USGA coined the term which numerically describes the difference in course rating difficulty between bogey and scratch players as the "Slope Rating," which is a second dimension in handicapping. Slope Rating is the slope of a regession line of total score versus USGA Handicap for a particular golf course. The Y-intercept is the USGA Course Rating which is the better half score average of scratch golfers. The slope of the scores line of an average course has been observed to be 1.13 and USGA Slope Rating is referenced as 113 to deal in whole numbers.

That would still be an extra step as people told you already and you still have not told anyone why you continue to annoy with questions like this-The basic question is WHY CONVERT TO 100 there is simply no need to do so. Pointless-But you cant let go you just get stuck on this. ENough dude go get laid or something.[quote name="MEfree" url="/t/69094/slope-why-not/18#post_880950"]The Pope of Slope website gives an explanation of how 113 is derived from a different point of view compared to the USGA site.  It says that the average slope is 1.13 which is multiplied by 100 to make it a round number.  My thinking is that they could have multiplied all slopes by 88.5 (or 88.49558) to make it a round number with the average being 100.

Not an extra step- it is the same number of steps to convert 1.13 to 113 as it is to convert 1.13 to 100 (both of which would be done by the USGA) and it is easier for the average person to divide by 100 rather than 113.

Oh brother. Dividing by 100 is irrelevant when they then have to multiply a decimal number by something like 1.17 or 0.93 or something.

Either way you slice it the formula works out to some decimal number ( whether your index or the score - CR or something) x some number, which is quite likely to be something greater or less than 1.0, whether either the denominator or numerator is 100 or 113.

Really done now.

    • Last year I made an excel that can easily measure with my own SG data the average score for each club of the tee. Even the difference in score if you aim more left or right with the same club. I like it because it can be tweaked to account for different kind of rough, trees, hazards, greens etc.     As an example, On Par 5's that you have fescue on both sides were you can count them as a water hazard (penalty or punch out sideways), unless 3 wood or hybrid lands in a wider area between the fescue you should always hit driver. With a shorter club you are going to hit a couple less balls in the fescue than driver but you are not going to offset the fact that 100% of the shots are going to be played 30 or more yards longer. Here is a 560 par 5. Driver distance 280 yards total, 3 wood 250, hybrid 220. Distance between fescue is 30 yards (pretty tight). Dispersion for Driver is 62 yards. 56 for 3 wood and 49 for hybrid. Aiming of course at the middle of the fairway (20 yards wide) with driver you are going to hit 34% of balls on the fescue (17% left/17% right). 48% to the fairway and the rest to the rough.  The average score is going to be around 5.14. Looking at the result with 3 wood and hybrid you are going to hit less balls in the fescue but because of having longer 2nd shots you are going to score slightly worst. 5.17 and 5.25 respectively.    Things changes when the fescue is taller and you are probably going to loose the ball so changing the penalty of hitting there playing a 3 wood or hybrid gives a better score in the hole.  Off course 30 yards between penalty hazards is way to small. You normally have 60 or more, in that cases the score is going to be more close to 5 and been the Driver the weapon of choice.  The point is to see that no matter how tight the hole is, depending on the hole sometimes Driver is the play and sometimes 6 irons is the play. Is easy to see that on easy holes, but holes like this:  you need to crunch the numbers to find the best strategy.     
    • Very much so. I think the intimidation factor that a lot of people feel playing against someone who's actually very good is significant. I know that Winged Foot pride themselves on the strength of the club. I think they have something like 40-50 players who are plus something. Club championships there are pretty competitive. Can't imagine Oakmont isn't similar. The more I think about this, the more likely it seems that this club is legit. Winning also breeds confidence and I'm sure the other clubs when they play this one are expecting to lose - that can easily become a self-fulfilling prophecy.
    • Ah ok I misunderstood. But you did bring to light an oversight on my part.
    • I was agreeing with you/jumping off from there.
