I would like to point out that I slightly mistyped in the previous post. That was the income graph. For income I agree that delta to last max is a good idea, because it can fluctuate quite a bit and sometimes conversion to mono or maxlev might even reduce it to zero for a quarter.
For CV I don't think this should be applied, but just the quarter to quarter delta. Ofc there is a number of stuff that can decrease CV like funding industries, building statues and so on, but I do not think they should be of influence of the points awarded for the next quarter.
