Why hash rate of R9 Fury X at flypool side does not tally with it shows on PC?

The worker ID lpw1 is two r9 fury x. It shows 967 h/s using claymore miner, but it greatly discounted at flypool.
The worker ID lpw3 is five RX 480 8g at 0.75 power limit due to power supply shortage. It is ok, since hash rate shows at pc side is 1480 h/s which is consistent with flypool side.

Anyone from flypool can explain this?
