It is overheating and throttling.
But 21.5w is a lot for standard 525mhz. What is the voltage you are running? It maybe set to high. 1150mV is standard.
You can run with 1100mV on 525mhz
I run my german bitaxes with 1100mV up to 600-625mhz.
I heard the china bitaxes are bad quality compared to german or swiss made. But even with china built bitaxes 15j/th should be possible.

how would i debug more? should i call the people i bought it from? my other 2 are at 18.49 J/Th and 15.99 J/Th while its still 20.2 J/Th but one is a 602 board

Are you in a particularly warm environment? Ensured the heatsink is seated properly? Otherwise I can't really see why the temps are behaving that way. 5.1V input suggests the power supply is fine. ASIC voltage is correct.
I let mine run for about an hour with the tab left open so it would log a good bit of data. You'll notice the frequency is a lot higher at 600MHz but my power draw is like 10% lower than yours with the commensurate efficiency improvement. You'll also notice the temperature is basically flat with a room temperature of about 25 celsius.
