Weight lifting: I'm doing the Super Slow Motion thing and I've got a question regarding muscle failure... Do I go until I fail once, or is it OK to do the next rep after going to fail and backing down?

I lift on machines (MedX), and usually go about 6 20 second reps (10 up, 10 down) for 2 minutes total. As I understand, I should go until I can't lift the weight all the way through the rep, and then quit. Hopefully that's rep 6.
However, if I'm on rep 5 and I lift 80% of the way through my range of motion and reach muscle failure (can't go no further). After 10 seconds of lowering the weights, should I go to 60% range of motion for lift 6? Or just call it quits.
I'm basically wondering if I'm actually reaching muscle failure, or if I should be moving up to a heavier load?
Also, I find that I'm progressing quickly in some areas, and not-at-all in others. Best bet is to back off the weight in the not-at-all areas even though I'm not reaching muscle failure in 2:30?
