I can't criticise the damage model in 1946, but I have to admit that on-line the P-47 has been most resistant to my 109's mk108 at about 250M, on more than one occasion too.
Interestingly the off-line results are more predictable with significant damage incurred, so I suspect that the model dynamics etc. have to accommodate many scenarios with differing results.
Maybe I should fly the P-47 on-line instead....
