how much do you add i bunker?
Start with 10 yards and keep notes regarding the lie percentage and the results.
Depends where the bunker is . . . if close to green +10 with bs . . . a wee bit more for elevations
In FW bunkers from 30% up, diminish...
...your expectations. You won't get out 100 yds - take the pill, take the wedge, try to save Par.
Crash,
Here is a pretty good discussion of bunker/sand work

I am using Cleveland wedges and find puttluck's figures overstated by 2-3% - i.e. I back off 2-3% and that shot is pretty close.
