we are not the same person.

we're telling you for your own good.
if you don't believe us, just try it.

for example, if you have two same rigs or even two same GPU-s, put them on the same pul.
just change miner rev, 4.0 on one, 6.1 on other, and put them on different adresses.
i can bet that you'll get at least 20% less hash on pool and also 20% less xmr in wallet with 6.1.

so, the question is: is this just sucky miner version, or clay raised fee?
