So what was the hardest part to understand? (just trying to figure out
how to better document this)

Looks fine if you want a hard 100KByte/s (ca 1Mbit/s) limit per user.
Usually how most people use delay pools is by using a somewhat bigger
bucket (maybe 10 times the rate) and a slightly smaller rate to allow
some burstiness which is typical in normal browsing while still limiting
downloads.

delay_parameters 1 -1/-1 400000/90000

this will allow users to access Internet in bursts of up to 400Kbyte
unlimited as long as they stay within their allowed 90Kbyte/s limit in
average.

You could also reorder the acl lists slightly to make them easier to
maintain if you need to add more exclusion criterias later on

delay_access 1 deny fastusers
delay_access 1 deny local
delay_access 1 allow all

but both ways works fine.
