Dealing with Margin of Error Need some guidance

I'm kinda stuck on how to move forward with this... not really sure what the margin of error is, if there even is one. Both recoveries checked out fine with their signatures, but the error margins are pretty different: First key: about 4.08% relative error Second key: around 24.6% relative error They both match up with Sig-R... should I just try to bring that down to 0% or what's the next step here?... - nonce checks out - hash generates the address - etc, etc... calculates Z and all that jazz.

Okay well updating - i have the nonce (validated) - Have the message hash (validated) - Have 2 sets of DER S R validated. - Pretty much have the entire model required .. BUT 2 odd things... Im having issues on the back end, its not matching for some reason, no its not the data..  The main issues are in the signature verification and key recovery methods.  IT did verify just came out with incorrect results which IT could be the point verification but have changed this out more times than i can count... The P2SH address deviation differed on a data resolve ... but the main compressed address remained the same.  IT still would be a hit and relevant but dont know why it would change. I want to get this over with and concluded. So any hints would be appriciated. Wish i could specify what and this or that, but i cant. I wouldnt trust my own mom with this one... but whoever helps will be tipped and can be glad they set something right from before... I really am wtf over it... its something trival...
