Frankly, I don't have an interest to say either way. But, I have run 10 D3s and 3 L3s for two days on Prohashing and then on Nicehash and on ZPool. The ZPool payout was more after the unpaid and pending amounts were considered (total earned). Not only was it more, it was substantially more. I will do a test later with screenshots, etc. But, there's no way that I feel like Z Pool is stealing from me. You have to make sure that you are considering the sum of your earned amounts.
For "true" testing, you have to run at same time your ASIC, on different pool ...
Not running them 24hours here / 24 hours here / 24 hours here ...
I made this test by my self, and i SAY IT, i have earn 20% LESS on zpool.
The reason that I posted at all was to say that ZPool didn't steal from me and I'll "say it." It's not a "true" test either to run separate miners on different pools for only 24 hours. You need more time. A week would be a good start. I'll try and run a test next week.
