Also sucks because letters after numbers a read as "units".
Just compare 5h, 3kg, 20cm, 9in, 1.3h
If your first reaction after seeing 0.99.7a 0.99.7b 0.99.7c was
that they were numbers in unrelated units a b c and cannot be
compared with each other, you need to get your head examined ;-).
I concede that it is a cute point you tried to make [*1*], but I
do not think your presentation was convincing enough.

*1* Which one is the heaviest, 5h, 3kg, or 20cm?
