The effects of Altitude

Postby JohnMeyer » Sat Apr 22, 2017 4:10 pm

Following on from a discussion in the OGT Discord and the Cherry Hills BETA thread I thought Id do a little definitive testing on the effects of altitude and how good the algorithm in PG is.

So:

Test conditions were basically 2 identical flat driving ranges, one at sea level, one at 1680m / 5183ft, Normal Fairways, Normal Greens

Test shots were launched using the OGT Shot app, using PGA Pro (Shankygolf) standard shot data for the following clubs: Driver, 5i, 9i, SW

Sea Level
Carry Total
D 251 270
5i 204 214
9i 149 154
SW 102 108

1580m / 5183 ft

Carry Total
D 265 300
5i 220 237
9i 163 169
SW 109 116

Gains
Carry Total
D 5.6% 11.1%
5i 7.8% 10.75%
9i 9.4% 9.7%
SW 6.9% 7.4%

Average gains: Carry = 7.4%, Total = 9.74%

When compared to this Trackman Academy video these numbers are actually very good indeed, and shows the algorithm is a credit to the PP developers.

Cheers for that info...but I do enjoy seeing the first shot sail off way further than you expect....and then you realise you're at altitude...just hope it's not a Par 3!!!

John if you don't mind I'd be interested in seeing what happens at roughly 1500-2000 feet and if the percentage is roughly in the middle, if there's a way you can test that.

Again looks pretty much as expected I would think. Havent got any reference to back that up though

Re: The effects of Altitude - driving range settings?

Postby bchafekar » Thu Sep 14, 2017 11:37 am

I live at 3000ft and definitely notice a difference here versus palm springs! that said - is there some way to set the altitude on the driving range so it's more in line with what I'm used to? Has someone maybe built a range at altitude? I've been checking out course forge and thinking about giving it a try if not....

Thanks!

No, you can not adjust the altitude. If you use OGT interface, you turn off Tournament mode and increase boost till it matches your local carry.
