60 h (2.5 days) Combining Catalyst / n Tournament Encounters, n from 10 through Stage 3, 8 through Stage 9, 5 for Stage 10.
Stage 10, that's better than 1 CC per completed 6-round Province.
I did 16 Provinces, now am trying for 24. That's 96 to 144 Encounters, 19 to 28 CC.
At 6 hours to produce a CC in the MA, that's 4.75 to 7 days worth of unboosted MA production.
