Handicapping Question - Mixed Tees

[xrayvizhen]

In our 9-hole league we normally play from the men’s (white) tees. However, a few older members are requesting they play from the senior tees. The question is, what adjustment, if any, should be made to their handicap for a particular round when they’re playing from those tees so they don’t get an unfair advantage over everyone else?

Here’s an example:

                          Par         Index     Slope

White Tees:        36           34.6       122       

Senior Tees:       36           32.6       113

It seems logical to me that those playing from the senior tees should have their handicap for that particular round reduced by some number, but what that number is, I’m not certain. Should it be 2 strokes, the difference between the two indexes or another number that’s a function of both the index and slope numbers? I looked at the USGA website in the handicapping section and it seems to indicate that as long as par is the same there should be no adjustment, but that doesn’t make sense at all to me.

If there's a simple formula to apply that anyone knows of, let me know.

This answer is easy to find. It’s right in the formula now.

Not an accurate summary of what the site says.

Tell me: assume a 12.1 index and run the formula for the two tees with the same par.

I used that calculator with one of the players in question, who has a 9-hole handicap of 11.8. The result was a course handicap of 8, which I assumed to mean, instead of him using his 12 handicap from the white tees he'd have a handicap of 8 from the senior tees. That makes sense. But then there was this:

"Since a Course Handicap represents the number of strokes received to play to par, an adjustment is only necessary if players are competing from tees with different pars."

That's what confused me.

That’s an adjustment… to the results you calculated.

Since par is the same you just play it as it calculates.

Ah, I get it now. Thanks.

Are you using the Ghin for maintaining everyone's handicap?
If so, the adjustments are indicated for the players.

Also, what scoring system do you use?
Spreadsheets are a good manner and can be customized to meet any requirements.
