I looked around online, What I found was a slew rate of a T34/85 was about 4.2 Revolutions a minute(As reported by the Russians). This translates to a traverse rate of 25.2 degrees per second (4.2 RPM * 360° per revolution / 60 seconds per minute). I did a few quick unscientific tests And I was getting better than five+ rotations a minute. Wartime Testing by the germans on captured tanks during the period reported a slower speed of approximately 1.5 RPM, which is about 9 degrees per second. So whos what the right slew rate needs to be. the 5+ RPMs I got feels to high for sure.
I would look at other tanks in AH...... but don't think I want to find out what numbers look like.
But on a positive note we did get the 60 round basic load correct.
But apparently only 9 to 16 of them were accessible from the turret ready rack in the turret.
