Many thanks to the folks here at TFP. I have successfully rewired my Hayward P4 to allow me to manage my Filter time, Heater and lights (thanks Jblizzle).
Yesterday my readings at 6 pm were: The pool was off for most of the day while I rewired and then I programmed the filter to run that evening (7p to 7a, @ 15% SWG) Pool temp is low 70's F.
This morning my readings are:
I'll check at the end of the day to see what my FC loss has been. I'm thinking I may need to bump my SWG to 20% and cut the pool run time down from 12 hours to 10 and then a bit more.
The reason I run at night is that we are billed based upon peak usage. (see chart).

Instead of running 24/7 my goal is to at least try for half the time and maybe get to 8 hours.
As the weather gets cooler I guess my FC loss will be less - is 1.5 PPM over the day seem reasonable?
