So how is this helpful then? Or did I miss something?
yes you miss
per console key and public key are making the signature (see ecuation for signature)
so (x) (y) = signature
this ecuation can be resolve because you have 2 unknown
but if you have per console key you can find out the public key
until now nobody know how to get the per console key
we need more experiments
