Yeah but all three are still very low - so it doesn't really matter.
I've no idea why our pool would get better HW numbers, but the numbers are too small to care about anyway.
HW relates to internal errors, not related to the work sent by the pool.
Also, the HW numbers are not really shown correctly by bitmain anyway.
The bitmain miner's internal nonces are not 1-diff, but whatever diff the driver sends to the fpga.
So you can't really tell from those numbers what % they really are.
If you are overclocking your hardware and getting high HW errors then you need to slow it down, otherwise, the number don't matter at all.
What actually matters is DiffR# / (DiffR# + DiffA#)
That's like the 2nd % number I show at the top left for shares.
In your case on that image the 2 numbers are:
129,448 / (129,448 + 82,447,800) = 0.16%
274,218 / (274,218 + 125,089,697) = 0.22%
