That accounted for 10.11% of your healing, for +11.25% HPS. An equal amount of Crit would have increased your HPS by +12.70%.
Though perhaps my reliability penalty of 90% for Mastery value is harsh; I made it so because it does not affect some of our more powerful spells that we'll be using in high-demand situations, such as EF. However, as you can see, it's worse even without the penalty.
Mastery also loses value due to not affecting Revival or DPS.
