The term you are looking for is "precision"- akin to reliability.
My experience is that BF Scales are not accurate for me and are NOT precise or reliable at all. But that is just my experience. I think they can tell progress alright, but I've always had erratic readings. This is not to discredit your insanity work!! It is definitely possible and realistic to lose 2% body fat following that program.
I would suggest you get a tape measure or even better- a set of calipers. You can estimate body fat % off of those readings, but they are numbers too and are another good way to gauge your progress, even if the scale isn't budging. I use a tape measure personally because I haven't found a good set of calipers that I can afford on a college kid's budget, and I LOVE it. Much more motivating in my opinion.
