Just got my R10 and was checking it with my G80 at the same time. For short irons the G80 is showing the ball going further than the R10.
For example: R10 chip shows 74 yards where the G80 shows 92/81 (Distance/Carry)
I have checked the club data and they match, so it must be a math issue. Ether the G80 is wrong or the R10 is.
It also could be launch angle. I don't see where to check the launch angle and my setup is not perfect and it seem the launch angle may be low.
In either case the carry distance on the G80 is still longer than the R10.
