So, GHQ has a triple-spin chance of over 90%, while BA has a chance below 30%. Just looking at that, and recalling my assurance that we only needed for BA to have half the chance of GHQ to keep up, we can see BA falls short (one third of GHQ, instead of one-half).
Why, then, do I say it's not as bad as we originally thought?
- The weight of missed spins in BA seems to impact heavily on non-chancetime spins. That means that, while Exp/Pero/Gift get less than half the amount of triple-spins than in GHQ, Chance Time chances are still on par with GHQ.
- Even though 1240sta in GHQ netted me barely enough triple-spins for 3*Chance Mission, and 2*Everything Else Missions, the spread of the spin results meant that I only managed to get 3*Chance and 1*Gift/Exp. I might have been able to sacrifice the last Chance Mission in exchange for getting all 1*, but I don't think a daily Kurito gift is worth sacrificing for a couple of N-WC...
On the other hand, today, by now 1200sta (I leveled up last night, so there's almost 300sta extra) have given me the 3*Chance and 1*Gift, with 2 spins on the 1*Exp.
What I can preliminarily get from this is that you can, more or less get the same missions on both sectors.
Added to that, comes the net Exp/Pero gains from each sector:
- GHQ: 1125exp, 4380pero
- BA: 1240exp, 5000pero
Which confirms my early thoughts on grinding, with bove 10% extra gains from BA.
