Great. Maybe you can consider re-wording it so others can understand. I
have no clue how 80bits is determined. The phase you quote is obtuse to
the casual user as well. If that means 16x5=80 irrespective of columns it
is not clear.

This may be a function of this not being considered user-space code but
something to exercise tests. But if we are going to publish it as an
extension its seems worthy of helping people decide when and how to use
them. The docs as written fail to do that - and reading the Wikipedia page
doesn't cut it either,
