digits

That means the digits in its decimal expansion (to pick a base) are not known to be normally distributed.

This means that it is not necessarily the case that every possible sequence of decimal digits is present in π.

For example, (apply #'+ (list 1 2 3 4)) means sum of the first four digits.

Technically, 10 + 26 + 26 = 62 files, since it uses string.ascii_letters and chains on digits.

Was the cost to replace/rewrite the systems in developer-years estimated in the single-digits, 10s, or 100s?

Being a normal number states more than that: any finite sequence of digits are uniformly distributed.

Then show your working in parallel for a large example, perhaps 40 digits.

Ha ha, not to worry, I did use the four digits on the front.

The coastline paradox is a matter of accuracy (significant digits).

(Skip any digits that you don't have a word for.) One of those should take slightly longer...

(Say, their decimal representation is at most three or four digits.) And suppose you know that x < y.

You then try 16 dictionary "words" whose hashes start with the digit found previously with different second digits.

Stopping even on the shoulder on a freeway is considered "risky" by most police officers and many (like triple digits) have been killed while stopped in the shoulder due to vehicles drifting, failing to pay attention, or otherwise being distracted.

Then trying to follow through the next part of the example you seem to have apparently arbitrary correction factors, so I have no idea what you mean by "errant digits", nor how you get these weird expansions in powers of (2.pi).
