That's the problem with reducing how you play to a mathematical formula. You need to know how to react to each situation that is presented. If you're just blindly following a formula, you might get more total production here and there but you gonna be losing something, somewhere else for making the wrong decision at that time. Chopping might give more production on standard but it doesn't mean chopping is always the right decision. It was before because Lumber Mill was really weak unless on a river, now it's viable. Something to consider is flexibility. Sacrificing total production to get a city with better production per turn, gives the player more flexibility to react to whatever is happening on his game. If I need to produce something at a specific time for whatever reason, I can. Chop is powerful but once you use it, it's gone. OP reduces the matter to which one will give more production in X turns and he doesn't see that production per turn have its own advantages that can't be reduced to a general formula.. I never said it was a record, just that it was pre-modern. You're reading it that way and giving importance to the turn I won because you seem to be incapable of looking at anything without your "quick wins master" glasses. It made zero sense to focus on the turn I won there, it make even less sense to bring that up here. What that has to do with chop vs lumber mills? Does chopping reduce the congress timer? Would I get a congress earlier if I chopped more? You're the one suggesting I should always chop without even considering any other variables. I'm not the one following a religion here. I chop when I need to, I go for lumber mills when I think it will be better for that specific scenario. You're not Newton and we're not talking about physical laws.
