General Representation of Destructions

Destructions where words or even the number of words cannot be reconstructed have to be represented by the following notation:

“--nQ--“ with “n” as count of destroyed quadrats.

Complete destruction of a line: “- -Rest_der_Zeile_zerstört- -“ ???

Examples
3 quadrats destroyed “--3Q--“
1,5 quadrats destroyed ”--1,5Q--“
