Why V has this code
V makes up about 1 per cent of English text, which is number 21 of 26 by frequency, against number 17 by length. Close enough that the code is doing its job for this letter.
The lengths were set by counting, not by theory - the alphabet page has that story.
Worth knowing about V
The rhythm of V is the opening of Beethoven's Fifth Symphony, three short and one long. During the Second World War the BBC used it as its station signal for the "V for Victory" campaign, and it is still the standard test transmission: VVV before a call.
