SkyTrak Distances vs Real Life

[BogeyMonster]

I wanted to share the distances the SkyTrak tells me vs what happens in reality:

CLUB	REAL DIST.	ST Dist.
1W	280	270
3W	250	250
3H	225	230
4I	190	230
5I	180	215
6I	170	205
7I	160	185
8I	150	155
9I	140	145
PW	130	130
AW	115	115
SW	90	95
LW	80	85

So basically, the SkyTrak is acceptably accurate with everything except my 4-7 irons, which it exaggerates by 15%-20%. It does this whether I am playing TGC2019 or if I am using the SkyTrak PC App. I assume this is normal, but who knows. It makes playing TGC2019 frustrating because there is ~30 yard gap between my 7 and 8 iron. Not to mention the ridiculous overlap between my 4I and 3H.

For reference, my driver is an M6, 3W and hybrid are M2, 4-AW irons are Apex CF16, and wedges are MD3s. For testing I used ProV1 balls on a CCE hitting mat. I don't know if I have a defective unit, or if the ST just does a poor job reading CF16 iron distances. Whatever the case, it is terribly inaccurate

For those of you with sudden changes of distance and/or spin numbers, it'd be nice to know what version of the SkyTrak app you're running, and what platform you're on (PC, iOS, etc.). Starting to wonder if there was some silent update of version on iOS or something.

AFAIK the ball flight model hasnt changed in a long long time, so that is unlikely. Coincidentally, both my kids started complaining that ST is coming up 10+ yards short. This started about two weeks ago. I haven't tried myself yet. My kids know their yardages very well, so I don't want to dismiss out of hand, but don't know what it could be.
