I was under the impression that the FW190 was an even better energy fighter, also the AI is very good at conserving energy in itself. Playing by the FW's rules might not be a good idea for survival. In P-51 vs P-51 it depends on the pilot. If you're good at dogfighting and your enemy in MP isnt, well, you just might want to get him to a turning fight. Therefore I think this is a bit too generalized.
Holding visual contact is most important, I have to agree :)
