yes my skipping is completely gone and I am the same as you, more slipping under heavy acceleration and/or with passenger on the back. I am 240 passenger about 130 - it makes a big difference. You will eliminate the slipping by tightening the belt. I got tot he point where I decided id tighten it until it went away or broke and Id put a chain on it, i was so annoyed. But, I got it 1?8 twist max- and its never slipped or worn anything and that was over a year and few thousand miles ago. Previously I took it to several shops that told me they couldnt recreate the slipping or that they adjusted belt to spec - either way, I'd just tighten it for 1/4 play to 1/8 play or educe the sag in half and take it out - if it gets better you know you are on the right track, if its gone, even better!
