Its definitely a rather big error, because its the performance of an early La-7! According to NII VVS tests, the max speed of the La-5FN varies between 610-626. Anyway, its quite unlikely that the speed of plane "39 210
375" is so much better than later ones, like the "39 210
495" or "39
211 257"
Regarding the weight, I agree, 3320-3340 kg is too much, but in my opinion, it should be between 3300-3320, like all examples in NII VVS tests.
