Service rating, indeed, not support rating.
I know the higher it gets, it affects the operational effectiveness of the planes, and less are available , because of maintenance.
However i learned to deal with a service rating 3, to operate the version 1 of the George quite effective.
These type 99-2 canons have bad accuracy, 23.
The machine guns have accuracy of 50
The 5 model has a machine gun in it, so it was probably missed in the 2 version.
Also the endurance drops from 351 to 330.
The extra maneuverability and climb rate is to be neglected as a decisive factor in my view, it is a very small change.
My worries are that it will do well against bombers, but suffer more against fighters, while at the moment the version 1 covers both angles. i even get a 1-1 or better result against the mighty thunderbolt.
The 1:1 you are achieving could have a lot to do with pilots and/or leaders.
The N1K2 is largely identical to the N1K1, except that the N1K1 has a higher ceiling and so is a better sweeper.
