+1!
And many are going to be amazed at the difference the correct -dcri value can make to what you thought was most profitable! (Power usage excepted)
I would set the decri range start @ 5.
This is true for Keccak and possibly for the other 2nd coins too from what I can tell. (Benching atm)
NB that the std test goes up in increments of 25.
I would set an increment to 5, (min 5 to max 40 (go higher if it sets 40...))
and then fine tune;
Range of 4 either way using an increment of 1 to find the optimum.
ie: if it chooses 35, set increment at 1, range 31 to 39... re test.
