Keep cranking it up.
I would start your pump early before sunrise and build up a bank of FC to use during the day.
CYA 60 FC target is 4. Your
Overnight Chlorine Loss Test showed you went into the night at 4 and had 3 in the morning. When you do that your SWG is playing catch-up the entire day trying to get back to 4 as the sun gets stronger as the day goes on.
You want your FC at 4-5 by sunrise so then the SWG just needs to maintain it.
Run your pump as much needed when dark to have at least 4-5 ppm at sunrise. More pump runtime and less % will work better.
