Tachibana's performance does not match Realistic's battle rate

Tachibana’s performance does not match Realistic’s battle rate. because There’s not enough ammunition, and the gun’s trajectory and rotation are bad.
If you want to maintain this performance, we suggest lowering the BR to 6.3 or 6.7

Is that the Nakajima Kikka? Sorry the name was got me searching through known names in game & out.

Anywho iirc it was originally for the longest time 6.3 an later 6.7 for a bit, I think it only just went to 7.0 this year.

So I’m not sure when it may return to a lower BR or go higher (knowing the devs due to some strange BR choices).
