It's Lanchester's Law. The smaller force takes disproprotionate losses.
If you fight four squads with two squads, you won't trade evenly. You'll lose both and they'll lose one.
It's why blobbing is so effective.
Your test is equivalent to throwing four Ostwinds at the T-34 in succession.

ps : And according to Lanchester's law, two Ostevints must be destroyed at the same time as the T-34/76, in order for Ostwint to have a quarter of effectiveness. In this case, according to the Law of Lancaster,
both of them survived, so they are about half the effectiveness
