Rule Machine - Get peer assistance here with setting up rules

I was trying to understand how the Rules Machine logic sequence works on controlling my 3 speed ceiling fan with the GE 12730 Z-Wave Smart Fan Control. Ideally I only want to change one setpoint temperature and every two degree increase trigger the next higher speed. The question is there a better way to do this than the way I did with three rules each having its own setpoint? I think it is possible my 3 rules are conflicting with each other because when I get to trigger on the next higher speed i.e. Medium speed this Fan 2nd Stage Cooling rule sets the device to 70% doesn’t the Low speed Fan 1st Stage Cooling rule try to keep changing it back to 25%? I am thinking this because in the second rule when have no actions for False what actually will reset the speed level to 25%? I may not be understanding the logic trigger point actions correctly.

FYI; The actual installation details are in this discussion Control 3-speed Ceiling Fan and Light Kit:
