Newb here with an s9 spaceheater and bitaxe looking for help.

The s9 spaceheater runs on Braiins OS, and the 'Best Share' is seemingly arbitrarily immediately 10000 and stays there regardless of how long I run it. The Solo CK Pool stats page shows my best share as close to 4 Billion. I've seen posts on reddit with a similar situation, but without replies.

Which is accurate? I found reference in the Braiins FAQ that they divert about 2% of hashes to their own pool when you mine on a pool outside of Braiins pool. That's fine with me for using their OS, I just don't want to be contributing 98%+ of my hashes to them...

Thanks in advance,
Pleb
