garyk49: Like I said earlier, maybe it's my club ball combo.
Nope - I dusted off my R11's and had the Slow Meter Cally, so played 3 rounds with them and a practice round (18 holes at St A's).
I did not have one serious variation from what I expected and how far the ball went. With the slower meter ball my ding percentage was pretty reasonable - including 9 in a row. But so no evidence anything strange.
Just a caveat on distance,(and something I know you will know) some holes play longer/shorter and depending on the wind, elevation and bounce there can be a large difference between what the club is rated and how far it goes. Prime example is the Par 5 on the back 9 at St A - i regularly have 250 to the pin and play as little as 195 rated club.
If you are getting crazy results I would clear your caches and cookies - sounds like a corrupt cookie there. Give your PC a good clean up, as I can assure you, something is wrong and most likely at your end.
