The weekend is over.
Didn't achieve my goal of getting to 3 mio PPD over the weekend.
(Some AMD GPUs got absymal low 0x16 WU instead of nice 0x17)
Good things are:
Good progress for a weekend, friday noon I started with 1 mio (which I did a month ago)
200 WU finished, no bad returns
the AMD GPUs run with x17 cores very stable
still room for further optimizations, planned for next weekend (+200k PPD)
improved my rank from 16300 to 1004
