Ok, I added the 20% bonus for SM, physics, and liberalism. It brings MM completion down to approximately T+40 (with an estimated increase in bpt from 617 to 700 on T+11).
I don't see how triggering a golden age will speed up this process any, since we'll need to generate an extra great person later and we may need to tech through guilds--chemistry if we don't get the GE on T+29. On the other hand, if we don't get the GM on T+11, it'll really slow down our tech rate from T+16 and on. Using the T+32 GPP to trigger a golden age post mass media (if no engineer) may be worthwhile though. In that case, we'll substitute the last GPP from marble for the 4th VC GPP (including our existing artist, scientist, and physics scientist). Note that we can substitute T+6 and T+22 with the physics scientist but we have NO replacement for the T+11 GM.
