TROLOLOLO
maybe it is hard to beleave but i do same mistake pretty often, maybe in little different manner, i raid enemy t1 mexes with t2 t3 units and i leaves lots of reclaim, and making that raid not worth at all
i think it is just hard, maybe you just need to have similar eco as your opponent, and just catch up to your opponent little later cause if you have map control you will still have more eco or at least more units on the field so you can eco safely a little longer
so that was about eco...
pretty much same about tech
i do not know anything, and do not want to analyse
so as anyone would answer question "when i get t2 land?" just when your opponent got t2 land you get t2 land too...
but why? obviosly because t2 units are better than t2 and even if you will have more map controll you will not able to fight cost effectively against enemy units
btw i didn't watched replay but i hope i helped a bit
just do not let your opponent run away with eco or tech, or you will end with t1 aa against t3 air or t1 land against exps
t3 mex is 13.5 1t mexes, so if enemy have couple of those he will have same amount of mass as if you would have whole map...
