To be real or not to be real?

[Maverick]

Set Optishot for real life distances or not?

[MrHogan]

I think people in general have a better estimation of their average distance more than they do their swing speed, most people see how far they hit the ball every weekend whereas swing speed for non-owning trackman is seen very rarely.

[MatalaWedge]

This is true.

Still stand behind my opinion that the distance is not that simple and that we need to know what kind of roll one is getting before making an estimate. Otherwise there will be variance.

[MatalaWedge]

From Maxxx's Pics following speed to distance ratios apply

274y / 103 mph = 2.66
269y / 101 mph = 2.66
267y / 103 mph = 2.59
270y / 110 mph = 2.45
279y / 104 mph = 2.68
251y / 97 mph = 2.58
267y / 104 mph = 2.56

From my early calcs of ball speed x smash factor x roll out % I think the ratio should be around 2.5 max so think these readings still show that distances still too far for the swing speeds acheived.

Hogan your 90% distance ratio may well be spot on after all this

Ill get on now and have a few hits and post my results, but definitely think were nearly there now with regards a setting for the distance % that can be applied across all sims. It will then be up to indivduals to be honest about if their swing speed reads correctly I guess

I think DD have done this cause they have not been able to model the roll properly. The ball is carrying further than it should (just under 10%) but not rolling.

Looking at Maxxes numbers I'm also feeling that 90 instead of 93 is probably going to be close. Probably my sample size this Morning was just not big enough...

[Maxxx]

When I get a chance , I will post my specs. Maybe 90% distance is the number ? I was hitting into a 1mph headwind so thats more lime 5 mph in DD's world 😂. And I was using a prov1 haha !

Cheers and good luck in in you final round dude !

Did some testing and results in pics. tried to vary my swing speeds from 3 quarter power to full blast and get a decent average across all 30 swings

Did each % setting in a different session, and average Swing Speed was pretty similar throughout each session

at 100% distance setting, speed to distance ratio was 2.72 - Too High

at 90% distance setting, speed to distance ratio was 2.52 - Very Slightly Too High

at 85% distance setting, speed to distance ratio was 2.44 - Slightly Too Low

had to finish my session after that as work called but think from this 89% distance setting will give the 2.48 ratio to swing speed which is a near perfect representation to real life as we will get

I would propose we all do testing just to see if this is the same across all peoples optishots.

This will then give a stock setting, for the distance %, and will then be up to individual to adjust speed % to best reflect their swing speed. I am happy that mine is near perfect at 100%, as you see I swing at 112 when blasting it to 90 at a bit more than 3/4 so 103 wont be far off at all.

id encourage you to do the test as I did and see how your results work out.

I just went into the range under calm conditions, FW speed medium and hit 10 drives at 100% distance setting. In the stats section in bottom right corner will then give you the averages as in the picture. I then backed out to main menu and started session again, changing to 90% distance and hit 10 more, and so on and so on

I hope 89% % distance setting will give everyone the 2.48 ish ratio that is true to life

cheers

Sorry if I'm slightly slow to understand, but would this mean that I would be at 90% distance ( cause we are probably pretty close to having the evidence to support it) and 92-93% (i have pretty much honed down to this being accurate with other ways of measurement) swing speed?

This in my opinion would be almost certain to produce less than real world numbers for my driver when it comes to actual drive distance... Not going to call it yet, but my gut is saying it's not even worth testing as it's pretty obvious from my point of view...

[JohnMeyer]

I would try leaving your swing speed at 100% to start with and dialling the distance to 89% and seeing what comes out in the stats section after 10 swings as your average swing speed and total distance. From this will see what the ratio is. Hopefully will be around 2.48 ish

If this is right then will just be a matter of adjusting your swing speed to what you think is best representation of your swing speed in real life.

The 2.48 ratio I think is a pretty standard and accepted ratio of swing speed to total distance in real life

You may just be lowering your swing speed too much on Optishot would be my guess if the distances come up shorter than you expect if the ratio is indeed around 2.48

It should give some nice results as like I said at the start I normally hit 265, at a swing speed of 105 when i was fitted, At 90% distance setting this was spot on, However if we just alter distance setting when my swing speed drops to 103, I then only hit 259 etc etc

89% will prob give the correct ratio, 90% ties in with my distances. Happy to err on the low side

I did 100% first then 90% then 85%. You can see as I get more tired the swing starts getting lazy and more outside in and the highest speed drops off

[MatalaWedge]

Don't think we can do both at the same time though... as I tryied to point out earlier.

I figure I should probably be at around 255-260m on average---> 279-284yd

At 92% speed 100%dist I'm at 290yd. ---> Probably slightly too much... and as I said earlier 90% speed is going to be pretty darn close.

If we then take another 10% off the distance then I'm going to be short (254yd) imho as I am "de facto" swinging it 115+ and am cabable of 120+.

I see what you are saying but I don't think we can have it both ways... I.E have correct distance through distance setting and then also have opti showing the correct swing speed...

[JohnMeyer]

yeah I see what your saying. I would suggest then as some peoples swing speeds ( Mine, Vega's and others) are reading what appears to be correctly, if you lower distance setting first to 89% or 90% but have you Swing speed at 100% and see what the results are. It may be you just need to lower you Speed percentage by a different amount. At least then we can get a fixed Distance % setting for everyone and start trying to fix the problem. It will no doubt not be a perfect solution but at least will help

May not work out right, not sure, and as you say may still be that shows your swing speed too fast, but if everyones system is at least set to give the real life ratio of 2.48 x swing speed by adjusting everyones' distance % the same,we will at least have a solid distance setting giving the correct club speed to distance ratio

It will then be a matter of those whos swing speed reads too fast/too slow to lower/raise it to a number they can "prove" is correct, ie like yourself who have a way to read it outside of optishot, or some individual trackman data etc. otherwise will just have to make do with what optishot says as no way to prove it is wrong really

[MatalaWedge]

2.48 is valid if we are all catching the sweet spot all the time. Some of us are doing it more often than others. I think this will disadvantege the better player somewhat as opti is basically assuming we are machines at hitting the center of the clubface.

The higher handicapped the player is the further he will probably be from the sweetspot on any given shot. I know this is probably a generalazation, but this probably still holds true most of the time.

This is not a big problem... also something we can't really help. Something we might keep in mind though...

[JohnMeyer]

Again agree completely. That really is the exact limitation off optishot, it portrays every shot as a clean hit, and as you rightly say something I think we just have to accept. Although I have noticed there are reductions in distances made in the software for toe and heel hits, all be it small ones

Have you had achance to swing at 100% speed, 90% distance?

[MatalaWedge]

LOL. I'm at "work". So no...

[JohnMeyer]

haha oh sorry, thought maybe like here in UK we sometimes get a day off day after new years day, especially if a Friday

That's just Scotland not whole UK it's to give you guys a chance to sober up ;-)

[JohnMeyer]

Haha, Im down near Norwich mate, however the same probably applies
