Sure, I'll be testing some related things on this front so I'll
try to produce some results that compare these two cases.

For the purposes of demonstrating this I'll choose the worst-case
scenario, that is, I'll ensure that the TX hash result exactly
distributes each RX hash preimage across all possible TX hash
values.

Cheers,
