I think it also really depends which bath-oil you use, and at what temperatures you ride.Fox is +0.05 to +0.15 for factory specs.
+0.10 is typical set not near end of bushing life
Ohlins does +0.18
Marzocchi used to be +0.20 over and that's where they had bushing slop but no failures
My personal ones are +0.14 and +0.18 for my forks..
For business I use +0.10 on everything... It's not compromising longevity..
Personal friends forks and buddies i race or ride with we will be +0.14 minimum , check the ride and if not flawless in stutter bumps and corners ill go up....
In california with 0W30, you probably want to stick to 0.07, and for sweden with motorex supergliss, 0.10+ would probably be nice.
