Default Proth/Robinson/Riesel

It still is'nt clear in definition, if primes of the form k*2^n-1 should be classified seperately from proth's k*2^n+1.

In the proth database the only distinction is +1 or, - 1.
I belive that K*2^n+/-1 are called Robinson primes.
I would post my findings and large primes here if this is the general case.
And if nobody opposes this generalization?
