Ren9077, if what you are saying is that it is always beneficial in the long term to upgrade your collectors to the maximum level possible as quickly as possible, then of course you are right. That's not always beneficial or even practical in the short term, but clearly a higher level drill will produce more, so the quicker you can get a higher level drill the better. You are forgoing production now for more production later by performing the upgrade, but assuming you play the game longer than 32 days that decision is always a good one.

It becomes a little more murky to try to play the math game of "If I start the upgrade during the catch-up period I can eliminate both at the same time" because all the catch-up point is is a modeling of an individual decision of whether or not to upgrade. You can combine them and make a composite decision tree if you like, but you since you don't actually have to make up 4 days of level 1 production, 6 days of level 2 production, etc. it's not really directly comparable in that way.
