Gave us:

But ISTR that when the decimal point was written by hand it was in
the air about half the height of the digits.

Not that I ever observed.

Typewriters and word
prorcessors did not offer that half-way character so a full stop was
used.

You're starting to scare me.

But is it more correct to handwrite the decimal point as half
way up the height of the digits?

Again, it is news to me.
