I still don't understand why you would confuse the number 8 with the
letter B? Particularly when you earlier said:
"Also as a scientist I'm much happier with suffixes because it would fit
with 180km or 7l, and again I'd prefer that there was no space between
the date and the suffix because this makes it much clearer on the page
where you have a date vs. a number."
...in which I first read "7l" as "seventy-one" and not "seven litres".
But I somewhow managed to cope with it.
