I like how you sorted that out and your reasoning behind it, Very logical and I almost outright want to agree with you except you forgot one variable

The Sherman Firefly!
Also I was reading that the first few years T-34's had terrible reliability. One unit had to move 3oo kilometers and lost half of its vehicles to breakdowns!
Also I know that T-34's didn't have radios in their tanks early on, the commander had flags he would wave for formation changes etc. That is why the Germans in under gunned tanks were able to hold on due to radios, training and therefore tactical superiority.
Also how fast was a t-34 compared to a MK IV or a Sherman?
I know its tracks were wider and much superior to the skinny Sherman and mark IV so mud and snow it would dominate the others.
