"A nuts month for CORZ doesn't look much better than a poor one for ARB with perspective."
I think you're mixing up two things - productivity and value. Looks like Core mined 1077 BTC with 7.5 EH, that's 144 per EH. ARB mined 172 with 1.6 EH so a much lower 108 per EH. So this does suggest a much better month for Core than for ARB but hopefully the poor Jan figures were just a one-off for ARB - but with the lack of decent commentary it's hard to tell. Anyway, that's only one part of efficiency and it may be that it is costing more for Core per EH (I haven't looked).
In any event comparing mcaps just on the relative number of coins mined in a month is not nearly enough to determine relative value - if only it was that straightforward!
