Old Man Yardages

[Burnsey]

I saw elite golf compared the GX and Autoflex .. is yours a GX blue ? I was thinking that would be the direction I would go.

At the end he was trying to hit all shafts as hard as possible. The Autoflex was quite stable, which suggested to me he could have stepped back from xx to x. The GX was over powered but I think that’s to be expected. The GX blue has a nice left bias .. which I prefer.

No, it's green.

The only condition I had at the fitting was I wanted 'sexy' shafts and the blue/red would not have passed but joking aside, that worked better for me. Mis spin and all that malarky.

He nailed the sexy with the AutoFlex rainbow

So....as mentioned in @Orikoru 's thread....I've been doing a bit of experimenting with driver loft to see if it makes a material difference in distance. My AiSmoke driver has a nominal loft of 9 degrees and can be adjusted -1/+2.

Whilst the distance gains were so subtle as to be non-existent (average distances at 8,9,10,11 degrees: 185.2, 185.4, 186.5, 186.9) there was a noticeable change in left to right distribution, with increasing lofts dragging the landing position from right to left (I'm right handed) with a 32ft miss right at 8 degrees loft moving across to a 25ft miss left at 11 degrees.

The chart below shows the distribution of shots. Red - 8 degrees, Green 9, Blue 10, Purple 11. Shots that I consider to be atypical and not wholly representative of the general distribution are circled in black. The four coloured X's represent the average of shot landing position, excluding those 4 outliers. It is plain to see that as loft increases, even for what is a relatively small set of data points, there is a definite tendency for the landing position to move left with a negligbile increase in distance. For me, on this occasion it is clear that a +1 (10 degree) setting is probably optimal.

Going to repeat the exercise with 3 wood and hybrid when I'm next up at the trackman place.

Good results, the only issue I would have is where the crosses have been placed. They may be the average based on the measurements, but they are not really where you are more likely to hit the ball. For example, I would expect you to hit the 10* club setting about 185 yards, and 20 yards left as this is roughly where half your shots landed. Similarly, I would expect you to be about 5-10 yards back from where the green cross is when you are on the 9* setting.

The left right measurement is FEET....if I'd used the same horizontal scale as vertical then the dots would have been a lot more congested and difficult to see the overall effect.

...what you say about the averages is not unreasonable....that's the trouble with statistics especially when working with what is a limited data set (unfortunately I have neither the time nor physical energy to work through the number of balls required in a single session to flesh out the data....but, even with the limited data that I have...the trends are pretty clear)...you can pick and choose how to analyse data....for example I could have used the 75th percentile measurement when determining if there were any yardage differences (75th percentile is what I believe Shot Scope users will know as Performance Average (P-Ave)...a measurement that helps to reduce the effect of outliers (especially bad shots) on the overall data set). If I'd used the 75th percentile to determine yardages then they would have been...

8 degrees...186.8
9 degrees...187.5
10 degress..188.1
11 degrees..191.1

Love seeing things like this it’s one of the reasons I bought the ShotScope and 2 rounds in I’m already addicted to the data and seeing what I can do with it to improve.

Looking at your data set it’s not a huge surprise to see the ball trending further left with the higher lofts as this closes the face at address so naturally maintaining that angle through the swing will create this shot pattern. I’d also argue that looking at it I’d be more inclined to go for the 11° setting, front to back dispersion is tighter and simple alignment correction on the tee returns those shots left of centre line which is consistent in its pattern apart from the one outlier and that’s optimal performance. 10° still seems to have a greater dispersion both sides of the centre line and more gaps front to back.

In feet the dispersion is much better!

Does your driver have a weight to counteract the closing of the face with loft? I have my Ping driver lofted up and the weight set to fade to balance it.

Yes....but I've not messed about moving it as part of this winters work. It may be something to try later on...the hosel is also set at the draw setting.

Too many variables!!!!!

(of which the biggest is undoubtedly me!!!!)

Sorry for what I am about to write .. it may be controversial .

During the swing the hands “fan” the club face. The opening or closing of the club due to loft can be mitigated by a slight change in ball position.

So the left bias suggests it’s shutting down quicker at impact
Right bias is the face is still open so hitting it later may reduce the angle of openness.

But you need to be aware of your swing path .. and adjust with that in mind.

Then you can select the loft based on the flight you want. Then follow that with working out how to change a shot shape on demand..

This works for me, because my swing path is very neutral.

But I am sure it doesn’t suit all so I will shut up.
