Yeah Phil... good to see 2 straight days of network hashrate drop... hopefully that trend will continue.  I just did some calcs and my 12 remaining 470s are still netting 40 cents per day per card profit.  Not a lot obviously but for cards that are fully depreciated, will likely keep them going at least through 2 more dags.  Luckily, i got my other 2 470 rigs converted over to a 6x 5600XT rig and a mixed rig with my lone 470 8GB, a 5600XT and the 2 5700's that i had to pull off my 5700XT rig due to a power supply issue.

On another related topic, is anyone here dual mining ETH + ZIL?  If so, can you provide a brief explanation or link on how it's done?  I've read that contrary to true dual mining (like the ETH + DCR i used to do), that it actually switches over to ZIL only for like 1 minute every 2-3 hours?  This seems strange to me and also, when i plug in numbers to a ZIL mining calculator, it always comes out at a loss, so there is probably something I am missing.  ZIL price has gone through the roof lately so seems like something to explore.
