Perfect
At least somebody understands what is required for a sump return.
If you ask a reputable skimmer mfg they will tell you to use a sump pump of the same value as the skimmers capacity, ie if you purchase a skimmer for a 400 gallon system it performs at its best at 400 gph passing across it, any more and its performance will be depleted. The 10 times turnover rate isn't correct if the tank is skimmed properly.
