130 versatility is 1% more healing and 0.5% less dmg
That's really not napkin math. mastery is 130/84.75 = 1.53 = 53% better than versatility? for heal per point of combat stat.
It pretty clear that's what pos was stating. After that, you have to look at the "bigger picture".
Now, if you have a spell that doesn't benefit from mastery and that spell accounts for 53% of your healing then you're at the breakpoint where mastery and versatility's "relative" values are equal.
Edit :
If rapid renewal is indeed still visible on logs (don't know about that), then it's easy to figure your stat prios.
