Using GAME Golf to Analyze Gaps

[saevel25]

I decided to take a look at yardage and club yardage gaps.

I took a look at my Game Golf for the information. If you go to your Insights page and under club performance you can look at how far each club goes. If you scroll over the yardage line you can see the distance on individual shots. What I did was I scrolled more towards my centralized numbers taking out the outliers. Sometimes Game Golf doesn't ditch some shots. Sometimes yardage on the insight page does not align with a shot on the actual course. If you miss-tag, or tag twice and delete one. I think Game Golf can create phantom shots. I have a 7 iron that went 284 yards. I went through each round, there is no shot for that. 

For the gaps, I used Excel and took some data points to calculate my gaps. Using the equation "=percentile.exc" I can calculate the 70% value. I took about 25-30 data points for each club. Finding out your yardage and gaps is a good thing to do from time to time. 

4-Iron: 225
5-Iron: 203
6-Iron: 203
7-Iron: 189
8-Iron: 176
9-Iron: 163
46* PW: 150
52* Edel: 132
56* Edel: 120
60* Edel: 108

The big thing I notice is I do not hit my 5 iron where it should fit. I might go to Golfsmith and have the loft measured. The club might just not feel right for me and I don't hit it as solid as my 6 iron. It is something to look into. It might be overly important because I don't hit the 5 iron that often. Maybe in looking into a less blade style iron might benefit for maintaining ball speed.

Funny ... I've been having a similar problem with my 5 iron for a long time as well.  I think it's because I mishit it the most and the reason why 4 iron doesn't also look bad is because it's numbers are mostly bolstered by tee shots on short holes.

My solution has been to just try and not suck.  Hasn't worked so far. :P

Edit:. It's because of this issue that my most memorable shots from the Newport Cup are three "perfect" 5-irons I hit in singles on 10,11 and 15. :)

Interesting, I have the same stats with my 5 and 6 irons, also.

152 yard avg. with both clubs.

But, I just began using GG this past Dec and have logged only 19 rounds under winter conditions.

I would think a trip to the golf store for a session with Trackman would most likely provide more accurate numbers.

That might be the case. My 4 iron is a more game improvement iron. It's a cavity back versus a muscle back. Also, I do use it off the tee more than the 5 iron, so the lie is perfect. 

Maybe my game is more suited for a more GI type iron in the long iron set. It's something to consider looking into.

Our distances are scary similar. The only difference is my 5 iron goes 206 and so does my 6 iron. I also prefer weaker lofts as opposed to the modern day 4 irons that are actually 1 irons. 

Oh and also I can't hit my wedges as far as I should be, mine are more like this:

60°: 80

56° 90

52°: 105

48°/PW: 125-130

Then there's a big jump to my 9 that goes 155-160

I think what you are doing is very important.  Sometimes defining values and organizing this information gives you clarity and a reference point to reflect on later as well as a way to plot your progress.  It eliminates the EGO and relies on unbiased data.  Awesome!  

Hitting a 7 iron 189 is crushing it.  I'm no physics major but I'm interested in your swing speed non the less.  I hit a 7 iron 167 if I tee it up and go at it 100%.  Using the excel calc is brilliant, I am going to do that later today.  Thanks for the post!

Driver swing speed of 111-120 depending on day, temp, moon alignment. Probably a 7 iron clubhead speed of 91-93.

Do you have GI irons and muscle back wedges? That could be the issue. I suspect your 9 iron is about 40-42 degrees. I had that issue with a major yardage gap between my shortest set club and my first Vokey wedge. I had difficulty managing shots in that gap.

When we talk about club distances we have to talk about lofts, too. My Cobra set has the stronger lofts: 30 degrees for the 7 iron; 20 degrees for the 4 iron. These are the equivalent to the older 5 and 2 irons, but I can hit the 4 iron off the deck because of the wonderful low CoG and tungsten weighting in the club, whereas I couldn't hit the old 2 irons off the deck very well anyway. Still my 4 iron is mostly a cheap driving iron.

My 9 iron is 44° and no they're players CB irons not super GI

My wedges are Nike VR Forged 60,56. Don't carry a 52° ATM as I broke the shaft of my 52° and am too lazy to find and buy a replacement shaft.

Did the same thing a few months ago. I determined inconsistent long iron gaps were due to tee shot bias and infrequent use. I hit a lot more approach shots with PW-6 than I do 5-4 and many of those tend to be recovery shots.

In fact I interchange 4i for a hybrid quite a bit just depends on the course and conditions. But same thing my gaps for 4h-2h nearly identical because the tags are mostly recovery shots. Almost every one on the left side of the red dot average.

My conclusion was GG does a good job of sorting it out without further dissection. Close enough to make decisions on the course. IME it's not usually as simple as find ball get yardage and pull club X. It's a baseline for all other considerations.

[onthehunt526]

I knew i forgot to get something with my taxes, crap, oh well.

I've heard mostly good things about Game Golf. @saevel25, most people's criticism, I've talked to that have it around here, was exactly that, having to manipulate the entered shots or getting a phantom 280 yard 7-iron...

I personally will stand up my alignment stick on the practice area and use my rangefinder, after i hit, say, 20 shots, pick up my outliers, pace of the depth and width of my ShotZone, find the center and shoot my alignment stick... probably +/- 1 yd, it's pretty damn accurate.

But I want to pick up Game Golf, just waiting 8-12 weeks for the prior returns to come back is gonna be long wait.

[Dave2512]

I don't have any weird shot tags I can't account for. GG tosses out the unusual stuff anyway, the insight averages determined by the majority of tagged shots in the middle of your range. Once you get enough in there you can sort different ranges of rounds and the numbers don't change much as the outliers come in and out.

@saevel25 Here is your 284yd 7-iron shot: http://www.gamegolf.com/player/saevel25/round/581799?shot_id=36649273&hole_id=19935780

Missed tag or cart path bouncer? Drive looks like it may have been into tree trouble for possible punch out.
