Best share from a few days solo mining my SP20s was 801,248,735. It was fun trying. They are now profit switching between NiceHash and Kano.is until the rental rates calm down, then they go into retirement (likely sometime later today).
Yep, I pointed the last of my SHA gear at the solo pool for the last ~13Hr just to see... I think only a share of 20M... lol
Was worth a chance though =)
