We know probability theory. We know that a private key is determined by probability conditions. We can, using probability theory, limit the search area for a private key.
1000000000..00000000000001 is possible but not real key.
101011011011..000111011001 more real key by theory.
so, for exampe, if we do 0b100000000 (tame) minus 0b10 (wild) we have a poor result 100% (a lot of 'zero' in PK is abnormal).
so, correct initial 'tame' and 'wild' values for huge PubKey is very important.
Amazing, I can't dispute this.
QQ: if I pick a number in my mind from 1 to 100, it is less likely to pick a number that has an abnormal amount of 0 or 1 (in base 2)?
