But why does that matter? Why would you not turn in F4?
Also, scouts are not penalized nearly as much for firing in F4 as strikes are. I often find myself firing starguard and clarion RFL in F4 as a bad habit from flying scouts this way. It allows me to track my target a lot better, but I think F1 is probably still a better choice in almost every situation for a strike. With scouts there are a ton of situations where firing in F4 is the best choice because the damage penalty is quite small.
