Live worker status equihash sol/s rate vs account equihash sol/s rate

Is it normal to have extrmemly different sol/s rates in the live worker status (1st section on the earnings tab) and the account hashrate (4th section on the earnings tab)? For example my live worker page shows a constant 42 to 45k sol/s but the account hashrate is all over the place but mostly around just 15 to 20k sol/s.

Thank you!
