Yes, in-floor cleaning system.
As that Hayward is a 1.65THP, medium-head pump, it will likely need to be run at near its highest speed to get the IFCS to function properly.
Yes, 1.65. With that being said, estimate of how long to run at max speed? 10k gal, enclosed pool area.
Only as long as it takes to get the pool clean. That's a trial-and-error job and different with every pool with a system like yours. At the lower speeds you should be able to get some circulation to get the benefit of a VSP.
Can you show the distributor valve?

3000 12psiCan you post the filter pressure at these speeds?
The manual should specify the flow and pressure for the system.

MaxFlo VS 500 Variable-Speed Pump
MaxFlo VS™ 500 variable-speed pump built with dual-voltage capability, is the newest addition to the MaxFlo pump family that provides significant savings over single-speed pumps. MaxFlo VS™ 500 is an easy drop-in upgrade.
12psi (at the filter) would not normally be enough to run any IFCS correctly that I know of…though it could be close. There are probably some valves set incorrectly for the IFCS…do you have valve automation and pictures (fill out your signature as mentioned earlier)? On the other hand, if your pool is caged and gets little debris (as many in Florida are), you may not need to run your IFCS at normal pressures to stir things up.
