A setting of 3 would be very long and only used by someone with restrictive lung problems that needed unusually long inspiration time at IPAP. Your move back to 2.0 is normal.
Personally (no lung problem) while still awake and going to sleep I sometimes like to take a very deep breath. With Timax of 2 the pressure drops while still inhaling. This is unpleasent, so I set it to the maximum.
