Don't rely on the ladder pitch lengths given in Northern Caves to work out the ropes required.
Add a generous amount (say 15m) for the traverse to the head of pitches and a further 10m for the height above floor level of the aforementioned traverses!
Thus each rope is 25 to 30 metres longer than the ladder pitch.
