It's not at all clear that div/mod by 20 calculations per roll are easier than base-20 addition per augment (or sitmod) -- though I suppose that'll partly depend on how common, and how large, modifiers are.
Now of course, if you just happened to make the game-scale one mastery = 10 TN increments (c.f. the 57 varieties of d10/d12 variant)...
Cheers,
Alex.
