yea,... as i was teling kuja in game, these figures are my own estimates.
I retested it just a while ago to see if the angles match up, and its pretty close i must say.
I don't have to go into the details, but I am sure there are many other better players than me that would agree that you can judge another plane's actions and even intentions quite accurately. Ask any good time anchors. Predicting enemy movement and when they fire would have to be second nature.
Anyway, I was just clarifying the point that you can control it just as much as director, but its just not as obvious as the director on how it works.
I hope by going into a lil detail, it can serve as a pointer to those who haven't already realized the different variables involved in the amount of spin.
