The fare evasion is not 6%, try doubling it! During evenings, there are lines with 25% ticketless travel and that is what is recorded/ discovered....
This coming from a man who wrote the revenue protection & security section for the recent tram bid for a bidder and got 100% score in both section!
The mean amount for fare evasion is 6%.
It is not obvious that during evenings it rises to perhaps 20%.
During the peak it falls to around 4%.
Many companies do try and massage the figure, but that 6% figure is what the PTE currently pay a scaled performance amount on.
That said my only concern is that moving figure is open to obvious and deliberate manipulation. Situation: TfGM staff collect data at Station A to measure ticketless travel. At station B, C, D, and E prior to that station, the operator sent it's staff to (co-incidentally) check tickets of those entering the trams. The 6% score is a perfectly valid one, despite your arguments. The morality of it though Simon, well...
