False.
OKW can get a Wstuka faster than OST even if pwerfer its in T3. OST teching is simply more expensive and takes even more time.
SWS (15)+ Mechanized (45) + WStuka (100) = 160Fu
BP1 (40) + BP2 (90) + T3(15) + PWerfer (85) = 250 Fu
And OST didnt build neither T1 nor T2 wich is pretty dumb. 222/250/251 or 250MHT are common sight on OST.
False.
How is 40+90+15+85 = 250?
Can you read? Or are you pretending to strawman?
As I said, noone rushes mechanical into stuka, that's asking to lose.
SWS (15) + Mechanized (45) + Luchs (60) (+ Puma (70)) + Stuka (100) = 220 fuel (290 fuel)
This build is really bad and you probably had no fuel all game if you didn't even get a t4 before stuka, so the stuka will either barely keep you in the game or you will still lose.
Assuming you are hellbent on rushing stuka and will rely on raketen and mines for AT:
SWS (15) + Mechanized (45) + Luchs (60) + SWS (15) + Schwerer (60) + Panz auth (60) + Stuka (100) = 335 Fuel (275 without luchs) (345 if you went puma instead of luchs)
Realistic pwerfer rush = BP1 (40) + T2 (20) + (probably a 222/251) (30) + BP2(90) + T3(15) + werfer (85) = 280 fuel. (250 without 30 fuel LV) (+ 10 Fuel for T1)
