These are very preliminary, we just layed something out to get started.  The whole point of this is to show the 'goldielocks' comp and reb force numbers needed at 2-5ips to keep bike stable. reb force 'just right' to allow slight overshoot at race sag comp force 'just right' to let it settle back to race sag The theory is we can achieve these numbers without a rebound separator valve or a return stack on cadj piston.
Using lev ratio at 100mm travel, or approximate race sag. Shooting for a linear increase in co wogas at 5ips. The spring rates are tweaked to achieve this linear force increase. This gives a low speed compression force relationship between the various leverage ratios at race sag. all are using 14 lbs 'target comp drag' and 17 lbs 'target reb drag' at 5ips approximate spring rate for 185+15 = 200 lb ride aa
