@jordyd@octodon.social yeah, rolling more dice makes the distribution approach normal
which basically means that 14d20 really wants to be close to the average expected value of 147. so the bytes you get from this method aren't uniformly random
what you really want is eight coin flips, one per bit
or four 1d4 rolls, or two 1d8 rolls and a 1d4 roll, turned to binary and concatenated together
@jordyd@octodon.social (i said byte instead of bit at first)
