Start at the lowest RPM and increase 100 RPMs at a time and note where skimming, the SWG, the heater, etc start to work. Add 100 RPMs to those speeds to account for less flow as the filter gets dirty and then that's the speed you need to run for any of those functions. The high one (likely the heater) satisfies all those below it, and so on. Any speed will filter and most of us with SWGs filter enough in the time it takes to produce enough FC for the day.
For many of us, both skimming and SWG works at a low speed around 1200 RPMs and we just leave the dang thing on 24/7 in the neighborhood of $20 a month for electricity. (Unless you need to heat, use water features, etc). Keep in mind, you're already using at least $10 of those bucks for bare minimum so it's really not much more.
SWG doesn't matter when, 4 FC added per 24 hours is fine, but for skimming, when matters alot and the when changes drastically. If it's windy for the 12 hours the pump is off, that's a long time for whatever blew in to get waterlogged and sink. So you can run a schedule and clean more, or just run 24/7 low and need to clean less.
