So long as u run the pump long enough for the swg to produce the fc you need its fine & likely plenty.
Be sure to stagger the pump & swg run times so the pump comes on before the swg & the swg goes off before the pump or else u will have a low flow condition & your swg will fail to run. Aka - turn on the pump & set it for 10hrs then an hour later turn on the swg & set it for 8hrs - this way u have a buffer where the pump is running for an hour before & after the swg is set so u know u will have flow.
You will need to be sure to reset this incase of power failure as those units do not reset themselves & will just remain off.
I personally like mine to skim while I’m awake & i am likely to be looking at/using the pool so I run my pump mostly during the day. From 9am to 9pm. Its probably overkill.
