Anyone else notice that v12/12.1 is reporting about a 5% higher hashrate than pool(flypool) for polaris based cards?

For example a 470 is reporting 280H/s miner side, and 260H/s poolside average. With 2% fee should be reporting ~275H/s.

Can anyone else on flypool with polaris cards confirm...want to see if its just me or a pool related issue.
