Thought it was 100mm or 4 inches when on the bike... Sure others have more or less. My bars are so narrow no one else will ride my bike lol
Rear suspension, 35mm static 100mm race , with no more than 10mm spring preload are the base industry standard for linkage bikes. If your numbers are in that range you are ok, preload play from there can give you the chopper feel (higher race sag number) or the push feel (lower sag number). Balance is the most important issue, the front needs to be correct as well. There is a complete sag thread here in the café somewhere and it follows the pro tuners standards pretty much to the number.
