Though for weekly tickets from Howdon/Wallsend it is £15.50 for a week but on the 1/11 from Howdon is is £13.35 or Wallsend (also on the Q3 and valid to Metrocentre) it is £11.65 so quite a bit cheaper for weekly tickets.
So even a small change could alter the whole dynamics of a commuters travel habits. I am guessing that's why the weekly tickets are priced like that.
