How can we verify this is only taking out a 1% dev fee? And what is the frequency of the 1% cut vs Claymore?

Even with the slightly higher hashrates, in comparison to Claymore, looks like Eminer profitability is much lower per my Ethermine.org Payout/Rounds dashboard. Also looks like Ether balance accumulates slower on this vs Claymore.

Has anyone else here noticed this? Taking "1%" every 10 minutes is very different from taking 1% every hour.

Please verify and respond.
