Read the headline of the table it is frequency in kHz vs. delaytime in
ms (milliseconds).

So these are 20.48 milliseconds.

If you are native english speaking, then Dieters fault is, that he used
in the english manual the german(latin) kind of writing numbers with a
comma, where the English are writing a point:
German 5 / 4 = 1,25
English 5 / 4 = 1.25
