I've been mining on Kano since Jan 21st with a single S9, but my shift graph seems to have maxed out at 8.9, I thought the ramp was a couple of weeks? I'm sure I'm missing something, but if the ramp time depends on us finding a block, then it was a bad time to switch...

Yeah, looks like a missing card. I run S9 and go between 13.5 and 16.
