Just ROI'ed in a little over 3.5 weeks.

Noticed I was trailing PPS on litecoinpool vs actual blocks I was generating (3 blocks in 11 days).
Tried one machine on NiceHash and another on tbdice. Mined a solo block on tbdice in 2 days, so I moved the other from NiceHash to tbdice. This morning mined another solo block. 4 blocks from the same L3+ in 3.5 weeks. Hopefully it is a golden goose.
