Jedi Knight Difficulty question

[RASAS]

Hi,

I'm playing JKA on Jedi Knight difficulty because Jedi difficulty has become too easy, however I've noticed something & I need confirmation,

why do reborn_new fight like reborn masters that are on Jedi difficulty, I've improved my skills enough to defeat up to 7 reborn masters in a gauntlet on Jedi difficulty in SP, however when I began playing on Jedi Knight difficulty I faced reborn_new in a practice duel on SP

and I've noticed they fight like reborn masters that are on Jedi difficulty, 

reborn masters are class_shadowtrooper duelists; in Jedi difficulty reborn_new are very easy to defeat;

so in Jedi Knight difficulty, do reborn_new really fight like reborn masters in Jedi difficulty ?

also should I still improve my skills in Jedi difficulty in SP until I can defeat more reborn masters than just 7 in a gauntlet ?
