Absence of the Symbol Resembling '4' in the Very First Folio 1r

[Dobri]

The number of occurrences of the symbol q followed by another symbol (or a short space and another symbol) is shown in the first attached image.

In most cases, the symbol q starts a new word token (it is preceded by a space or starts a word token in a new row).

There is a small number of exceptions when the symbol q is preceded by another symbol (or another symbol and a short space) as shown in the second attached image. 
Occasionally, said preceding symbol is a part of a longer prefix.
