If you can afford to, I'd increase in 5-10mm increments. If you're on a budget and a bit of a painslut, 15mm increments is probably the max. More than that and you might not be able to fit it without tearing IMO. I wasn't nearly as careful while training myself so YMMV. I'm up to 50-60mm comfortably and a maximum of about 85mm. Stopped stretching for the most part though. Good luck.
