The guide says that you should never FLU on an Attribute Level since it will cause you to lose that point. Of course with the Uber-ness of most of the Jedi here that one point won't make much difference, but the lack of a Master Feat + Power on that level can get a little annoying.
I'm here to say that FLUing on an Attribute Level and keeping that stat point is entirely possible. As long as you RLU on an Attribute Level, you still get the point you would have missed otherwise. Of course this means you'll need to RLU on a level with Attribute, Feat, and Power gains, and I'm not sure how many of these there are.
