Performance factor - stats

[Rooter]

in the ask the experts section, there is a discussion on how many putt per round (PPR) should a low capper do.. most of the answers are, well it depends on how many Green in regulation (GIR) you hit. But then in turn, how many greens you hit, probably comes from how many fairways in regulation (FIR) you hit.. So stats all have an impact on the next one.. So i started thinking, can you calculate a "performance factor" for your play..

I am not a mathematician, but i am sure it can be done quite easily. So come on then bean counters, give me a formula! i have tried, by my simple brain cant compute..

Would like to see FIR + GIR and 1 putt = 100%, FIR + GIR and 2 putt = 75%, Missed FIR but Hit GIR and 1 put = say 66%

am i making a "solution" to a problem that doesn't exist, or am i on to something?

I think a job as a statistician beckons on the US PGA tour for you :thup:

surely the latter would be better ?

There are a few of the Score keeping apps that identify this sort of thing

Scoresaver 2 is one of them I believe

I like the way you've structured it but surely as an overall performance factor, the score is the measure.

FIR is a fairly absolute measure in so much as it starts with a good lie.
GIR, I believe, should only be measured from the fairway - having the rough in the equation just clouds how good the golfer is.
You could measure GIR from the rough as a seperate criteria - recovery play.
Pitching & chipping, e.g. the 3rd shot on a par 4...
Then its putts per GIR & putts following a recovery & pitch/chip.

They'll all give an idea on what needs to be worked on but, as per above, the performance factor is the overall score against par IMHO.

Scoresaver 2 has them all separate and more stats, but i was thinking of a single combined figure worked out from a combination of the 3 factors.

Absolutely right, but this would show you how you got there and what you need to improve on the potentially lower your score more. you could drive a par 4 and then 3 stab for par. yes its a par so 100%, but its about the deeper analysis of getting to the goal. I know the saying "doesn't say on the score card how it got there" for that hole you played like a knob but somehow managed a par..

keep the ideas coming! am a whizz on excel but not the math! i am thinking we need some square root shizzle going on in this!

As a bean counter/mathematician, I think there's a few too many variables to come up with a single/simple formula and it will always be open to suggestion or interpretation!

The simplest idea I came up with was to assign 33% to each section, so if you hit the fairway it would give you 33% from the fairway you then hit the green it becomes 66% (simple so far!) ok putting I'd use the reciprocal so a 1putt would be 1/1, a 2 putt 1/2, a 3 putt 1/3 and so on multiplied by 33% so I guess the formula would be :-

(Fx33)+(Gx33)+(1/Px33)= PF%

<<2nd edit>> you could change the %ages up or down depending how much importance you place on each section! I still don't think this is foolproof and won't be selling it to the PGATour quite yet!

the F & G would either 1's or 0's depending on whether you'd hit the fairway or green, while the P would be the actual number of putts

 

[Hobbit]

But what would a birdie do to the calcs? How can you have greater than 100%?

Hobbit is right when he says the overall 'factor' is your score. The best golfer is the one with the lowest score. Presumably what you want this index for is to split out performance across different parts of your game so you know, for instance, who is best off the tee etc.

In my mind, you want something like strokes gained putting but extended for all shots. So for instance, I'm on a par 4 and I might be expected to average 4.2 on the hole. I pull my drive into the rough from where I might need on average 3.7 strokes to get down. My drive has cost me 0.5 of a shot. I then play a great iron shot and just miss the green to a spot I take 2.1 strokes from. My iron is +0.6 strokes now. I hit a poor chip to 8 ft, where I take 1.5 putts from typically, for a -0.4 chip. I then sink the putt for par and +0.5.

-0.5 + 0.6 - 0.4 + 0.5 = +0.2 strokes gained for the hole

Stopped recording my stats recently and seem to be playing with more freedom. Coincidence nest pas

true. its no help to stand on the tee in full knowledge that you have missed the last 5 fairways. it just heaps more pressure on yourself.

Your play changes every round so no, I don't think you can have one performance factor. There's only one important number and that's your score. Being aware of your weaknesses is important but knowing your percentage over several weeks isn't IMHO.

 

[Hobbit]

Knowing your weaknesses gives you the opportunitiy to work on them outside of a competitive round. And it also helps you with course mgt, e.g. I struglle to fly the bunker at 340yds into the wind, therefore I should lay up with a 5 iron to 290yds...

 

[Rooter]

hmm great feedback guys. will keep pondering!

This makes some kind of sense to me, although I'm in no way a mathematician. So here's a stupid question: would the formula above only give you a PF for each hole in isolation? If so, how would you then apply it to an entire round - simply multiply by 18, or is it more complicated than that?

INTO the wind? Are you sure??

Hmm, more thinking for my tiny little brain! but watch this space a new performance management metric will be coming out soon! suggestions on the name please...
