Obelisk grn1 profit different

Hello, I would like to ask what the real profit original site OBELISK vs other site




For OBELISK GRN1 mini 7$ day ( OBELISK)
54$ day ( asicminervalue )


I think Obelisk site calculation is correct. 54$ per day means 18 Grins approx which is not even current day reward for 70GPS hash rate.

Obelisk site is 7$ not 54$

Is correct?

How is the Obelisk now showing 7$ profit per day when the Obelisk GRN1 mini has the power of the C31 70GPS? And the Innosilicon G32 Mini has a power of only 21.5GPS and a profit of 18 $ per day?
