Don't forget that the judges are mere humans... and the judging, as I have often witnessed (even at international competitions), does not go always exactly by the book.
One example: if a "no-name" pilot is among the first ones to fly, and manages a nearly perfect flight (not talking about myself here!), the judges tend to be cautious in giving high marks (apparently reserving them for the "big name" pilots). Another one: local "heroes" tend to win competition, even if the consensus among pilots can be that there was someone else much more deserving. If you want one more, "big names" are often only lightly penalized for rather big mistakes - not many judges have the guts to zero CPLR for a doubtful snap roll...
Constant speed flying is something that might just help you show the judges that you belong in the "great pilots" club and maybe subliminally bias them in your favor. In any case, it cannot hurt so why not to try..
