A way I have seen for setting rebound and compression is the half way method, set sag first then set rebound leaving compression alone. to set rebound ride a section of trail with rebound fully open, then ride same section with fully closed, which felt better? If fully open, next step is to set rebound halfway between what fully open and fully closed and ride same section again, which felt better, fully open or halfway? If halfway felt better, next step is to do same run comparing halfway setting and half way between halfway and fully open, keep doing this until you run out of setting change. first run 0 against 12 clicks, assuming 12 clicks of adjustment, 0 clicks felt best, next run 0 clicks against 6 clicks, 6 clicks feels best, then run 3 clicks against 6 clicks, 3 clicks feels better, next run 3 clicks against 5 clicks, 3 clicks feels best, run 3 clicks against 4 clicks, the one that feels best is the right rebound for you. then repeat for compression, long winded but hope it makes sense, better explanation can be found in Brian Lopes book.
