You have started projecting your own flaws on to other.
SOV teching costs without side techs
15+75+100 = 190
OST teching costs without T2
50+105+40 = 195
SOV teching cost to T4 + sidetech and mobilize reserves (cuz LV skip)
15+15+75+20+100 = 225
OST teching cost to T3
50+105+20 = 175
OST teching cost to T4
50+20+105+40 = 205
SOV teching cost with T-70 + molly/AT
15+15+75+70+100 = 275
OST teching cost to T4 with 222/flametruck
50+20+30+105+40 = 245
SOV teching cost to first T-34
15+75+100+90+15 = 295(305 with mobilize reserves since LV skip)
OST teching cost to first P4
50+20+105+120 = 295
