So...  IF i have a matching R on the lattice against the signature is that enough to say its valid?   It does display a key but im trying to confirm the results before i bother converting it.
It seems the lattice doesnt like adding in the publickey into the formula and fails on add and inverse functions..   

That all being said, i did it to 2 sigs and they both came back with a matching R ... then went to test on something else which failed... so that proofs it half way i guess..
Just want to know if the R matching is enough or if there is another method to confirm the result... ??
