Sorry, we probably chose the wrong words, the diff / 8388608 marked some valid shares invalid (block candidates) on our side which was not happening with / 65536 so you should simply find more block candidates with the mod.
Best thing is probably to just try the miner without the mod and with the mod, for example point two comparable machines one to block quarry and one to our pool and you should notice a difference in speed, recognized shares, shorter rounds and lastly also the payouts.
Thank you for the clarification, that explains some of it. Then there is no need for me to compare anything, the miner is not faster just incompatible.
Most likely the errors you encountered is because MPOS is not configured properly. My guess is that you have your pool set to Scrypt so it is using a target bits of 16. Whereas for this coin and miner we are using 9 because of the much lower difficulty.
The other differences you talk about are merely share rates configurable within NOMP (or whatever stratum you use). Yes, you can make the results look more consistent by increasing rounds etc but it still averages out the same. There is no hashing speed increase. I assume Suprnova also uses different settings for that as well, but again, no speed increase will result.
You could have just asked us or suprnova, we would have tried to help you get past that problem. No need for ridiculous claims.
