Max, my power for longer durations was never affected by weight loss even when I was down around 66kgs, not sure what my 5's - 1 min power would be like at that weight as I never spent much time training it,
but at 73kg I set both 5's and 1 min bests, and no doubt I will set new pb's in the coming months when I start to freshen up for the RR season and by then I'll be at my usual fighting weight of ~73kg,
I might try to drop a little more this season but it's stressful and not pleasant training hard for long periods of time when your consistantly running a calorie deficit,
for me it's never a concern of loosing power but loosing the ability to rack up quality training, I train hard and I train alot, the thing is that the fitter you get the harder it is to maintain that fitness and it's even harder to improve fitness, add to that an extended weight loss program and BAD things tend to happen.
