It's fairly obvious...

if you are simply doing:

(t/T) * 360

Which is what I think you're doing... then that is the same as:

(t*360) / T

Now (t*360) isn't going to be smaller that T... There has always been something that has bothered me about teachers, I think this example probably explains why!!!! I probably shouldn't have answered this question, I should have let you sweat it out a bit more, but I'm just too kind for that!
