Infinito3010:
I expected a number between 120-135 not including putts.
I'll give updated numbers over the course of 3 balls, with a detailed breakdown on type of stroke play played. Including, Random-3, CTTH, Alt-shot, etc, any type of golf I play.
I can confirm both the 2.5-dot callaway z and i balls last 120 hits each. The legend callaways are 2-dot, so a reasonable guess would be around 110 hits.
The easiest way to count hits is to use the stat page alongside the scorecard in a stroke play. You can find total number of stokes and total putts. So all the numbers I reported in my post are number of strokes minus number of putts.
I found only putt from green (not fringe or fairway) counts as putt in stat page.
I also found it's pretty accurate that the durability bar turns red at 25%. I tested a 120-hit ball and the bar turned red after exactly 90 hits.
Hope this info help.
