Hi chia, Thanks for the feedback,
chia_00: I have added a new optional argument --random-seed <SEED> (default: 0) to let users set the seed manually. The default value of 0 ensures deterministic, reproducible benchmark runs by default. chia_01: I have updated the Motivation section in the KIP to elaborate on the practical use cases for each key distribution mode.
