Can I call shenanigans on that 2014-01-29 660 TI added to the spreadsheet? I find it very unlikely that a stock 2GB card running the 12-18-2013 build is going to get 409Kh/s (79Kh/s faster then the top 660 TI)
Possibly.
The hashrate spreadsheets are pretty outdated and sometimes weird results are being uploaded and to be honest I completely lost interest in scrypt. I'll keep maintaining them like once a week but don't expect any upgrades from me on my own. However, if you suggest something useful I'll gladly do it.
The reason I abandoned scrypt completely is that I have a low-mid range card, which is a GTX 660 and these cards have much better scrypt-jane performance compared to scrypt performance.
So for example a 780 Ti hits like, I don't know, let's say 700+ khashes/s doing scrypt and 5 khashes doing scrypt-jane while a 660 gets 260 in scrypt and 3.4 in jane so a 660 is 2,7 times slower in scrypt but only 1,4 times slower in scrypt-jane which means mid cards are better off with scrypt-jane and high end cards should probably go with scrypt.
On another note, I'm sticking with the old autotune method because the new one seems to do weird things. Could be because of the 1% backoff value instead of 12, not sure.
Edit: Oh, the microcoin difficulty stopped dropping and started climbing back up (3.59 -> 2.2). Found 10 blocks these two days with roughly 360-400 kH/s.
