Yep, so once the deflection occurs the spring rate is the is the same for the compressed distance of the spring regardless of preload as the preload has been overcome, with gas pressure, the rate is progressive due to the compressibility of gas just like oil height in the legs. So by not having a float, you are hoping to have enough pressure to back fill with the spring preload static pressure, and with gas the same, where as kyb/ Showa are lower/zero static and therefore need a float to backfill quickly on rod movement due to the very fast ramp in pressure due to the spring loading up, hence why main spring preload is around 10mm stock on jap bikes and 5mm on the zokes. Brain exploded.
