Come now, you just can't be as thick as a brick, despite how you continue to misrepresent what I'm saying.
"My prediction for what will happen if pintle effectiveness is reduced, and vulnerability is increased is exactly what AKWarp tells us is already happening. The N1K GV vulchers will be out in force."
The problem here is possibly two fold:
1. The GV's need cover to hide in from airpower, as they historically did.
2. (Possibly) GV armor needs more tweaking to make it more historically correct, more protection against aircraft guns.
So your solution is to artificially increase the effectiveness of the
pintle gun? 
As to the rest.........
"only a limited number of GVs."
You can't seriously offer this as a reason to incorrectly model the ballistics of a gun. So anything limited in number should get a cheat code? I'm very close to ROFL......
"The Hurri-1 was not designed to be used in 1945."
Really? I'm pretty sure tanks were not designed to suppress air power either. The pintle gun mounted as "AA defense" is more truly just a gesture made at reassuring the tank crew. As I said, who'd want to stand in an open turret manning that thing when .50's or 20mm were raining down all over and around the tank?
Beyond that though.. thanks for stepping up and proving Ack-Ack right in the other thread by once again advocating an RPS.
Now I AM ROFL!
