Neither of you have provided an actual private key for the uncompressed public key, so no one can verify that these keys are "next to each other". All this looks very much like ill-conceived quackery, where one person creates two accounts to prove his point in some ridiculous way.
I hope you are not talking about me here, and I hope you know that if you add 1 to your public key, you have actually added 1 to your private key, but you already knew that right?
If either of us knew the private key of a randomly given public key, we wouldn't be here would we?
Just let me find out how this backdoor fella is going to divide a key by x 0.5ing it. Lol.
