Speed of simulation

I use SPAD.neXt and I went so far as to bind a combination of the trigger button on my left yoke handle (Honeycomb Alpha) with the rotary knob on my Bravo to set the sim rate. Then after the INCR or DECR command is sent, it reads back the current simulation rate audibly. It seems to have gotten better after the last update, but the “simulation rate” is not always the same… Its usually “2.0” when at normal speed (referenced by clock in aircraft) but sometimes it might be 1.0 or 0.5
