Assuming neutral riding position, with 15 lbs gear on.
Weights of upgrades (battery, controller, etc) to be added to rider weight
Stock bike with 18/21 wheels
Riders close to a weight cut off need to adjust preload to compensate
Very aggressive/pro riders to consider +1 weight class and drop preload to get sag, especially if in the upper range.
Rider preference and riding conditions may require a different setup

Example:

190 lb rider without gear, 20 additional lbs with upgraded controller/battery
Weight calculation 190+20 = 210
Aggressive rider = Heavy tune with low preload
Relaxed rider = Medium tune with high preload
