It's a genuine question to see what number span people are using to
remember random numbers.

It depends on the structure of the number. eg:

55-67-99
132-231
1000-44
9-88888
27-288-9

Yes, if the number is already separated by hyphens/spaces, those are
the chunks that I try to memorise.

Apparently when the GPO started issuing phone numbers that were longer
than a couple of digits, they did some research and found that people
could remember chunks of either 2 or 3 digits, but a 4-digit chunk was
harder to remember.

I'm not sure why the UK read a chunk as a stream of digits
(one-two-seven [pause] three-four-one) whereas European countries
assign tens-and-units significance to pairs of digits (twelve [pause]
seventy-three [pause] forty-one).

German has the problem of its "four and twenty blackbirds" reversal of
tens and units - you hear drei-und-siebzig (three and seventy) but you
write down 73 in the opposite order.

Most Germans have a mental buffer, waiting until they hear both numbers
in the pair before writing down the digits. But I noticed one German
writing down the digits in the order that he heard them: first the
units, then the tens digit to the left of it; skip three spaces
forwards for next unit and back one for tens. This
three-steps-forwards, one-step-back thing seemed to be very cumbersome.


French falls foul of ambiguity because of its quatre-vignts notation
for 80: quatre vignts dix could be any of:

quatre-vignts-dix-huit (98)
quatre-vignts dix-huit (80 18)

A pause makes all the difference. I imagine that French speakers make a
very exaggerated pause in the second case to avoid ambiguity, whereas
almost no pause is needed between non-ambiguous pairs such as
vignt-huit trente-quatre (28 34).

To add to the confusion, two of the letters in your French '20' are also
consistently reversed!
