Your Q that you have just linked to says this:
guys lets say 32 divisors will return 32 keys , one of will be guaranteed for lower range but what about other all keys , i guess they all are also valid ~~ so my question is all other keys are random in 256 range or what?
from here, my answer were no random, and exact in all 256bit range, and what is exact location, i explain about how to calc exact range, simple, bro if you mislead by my those answers and explanation, i love to say SORRY
