FYI:

I downloaded the new master copy of the mining program from github. (https://github.com/aaronsace/MultiPoolMiner)  I wanted to see if the changes you talked about would make a difference in the calculations, because I was getting failure to connect to zpool API.

I put it on one box with the RX570 and let it run overnight, and the benchmarking was completed.  The numbers seem to be more accurate.  RX-570 at 600 H/s is calculating at 0.00011 BTC.  Based upon the reported hashrate, that looks good.  (I know I will need to update the bios to get more out of this card in terms of hash/second, but that was not the point of this post.)

I then tried to run the new master version on three Nvidia boxes.  All of them failed, because they got stuck on EthDcr64.exe failed to find libcurl.dll.  Comparing the bin directory from the old version to the new version, it appears that there is stuff missing on in the .\bin\ethhash-claymore directory.  I copied everything from my old version for that directory, and now all 4 boxes are humming along.

I can't comment on how accurate the nvidia calculations are yet, because those boxes are still benchmarking.  But, preliminarily, the numbers look more around what I would expect.  I will report back when it is done.
