> luck streak

is this a technical thing or just a figure of speech? 

I know I can just ask AI, but I prefer to zap Opti for an answer :-)

I was for a moment worried that there would be stales, but no. The good news is that at 10EH, the "TIDES" window in which your shares count is like 4 days or so, so at least you've not lost work, yet. You need a block within a day or so though or some shares may go unpaid (which is shitty if you had a luck streak with those shares)

optimism

I tend to chirp when Ocean goes on a hot streak, so I need to be even handed and mention that they haven't hit a block since January 30. I think this is the longest drought I have seen since I joined the pool.
