All are within good ranges. Let your FC drop a bit and keep your pH on the 7s.

Your pump runtime is determined by several factors, primarily how good the water looks. If you can keep the water just as clear, and free of leaves, at four hours as you can at eight hours, then set your runtime at 4 hours. If the water starts to look dingy, or leaves are not getting skimmed, then increase your runtime until you are happy with the water quality. Then adjust your SWG to produce the desired FC within that runtime. The less you run your pump, the better your electric bill!
If your SWG cannot produce the desired FC at the runtime you want to use, then you have to increase the runtime until it does.
So it's a combo of fooling with the runtime and the SWG output until you get both a clean pool and proper FC. Unless you don't care about your electricity bill...
And then you'll have to repeat the process as the seasons change. Colder weather means less need for FC production. Fall might mean more leaves. Summer means more people in the pool so more need for filtering and FC. Etc.
Every pool is different, every set of conditions are different. Which is why we can't just tell you what numbers to use. You have to do your own trial and error. Just track your numbers as you are doing, and after a year or two, the patterns will emerge.
While experimenting, keep the FC on the high side of your target range. What you don't want is for your experimenting to leave your FC so low at some point that you get an algae bloom. Better to play it safe until you are more confident with your numbers, and then you can ease them down a bit if you like. Many of us run our FC a little hot, just so we never get anywhere near the "algae threshold." So while you might use up a little more life of your SWG by doing that, for some of us that's worth it, to never have to worry about getting algae.
If you fill in your signature, we can better analyze your equipment setup and perhaps offer some other tips.
A signature something like mine is especially helpful to our advice-givers.
For example, some here with a variable speed pump, find that running for 24 hours a day is beneficial, and they set their pump RPMs and SWGs way down low. I like to run my pump as little as possible. Just personal preference.
