   No, I realise that - which is why I said *active* lines. I've since heard   
   that the number of active lines for the 405 system was 377. And I know that   
   for the 625 system it's 575. But neither 405/625 nor 377/575 is a nice round   
   fraction, which suggests that the averaging algorithm must have been   
   horrendous.
