I have some serious concerns with the Monthly Snapshots in terms of survey methodology and robustness and whether it is a true reflection. It is an unknown in so many respects. The monthly snapshots actually form much of the TransLink tracker so it is important we come to terms with this.
Contrast the TransLink approach to Transperth Annual Passenger Satisfaction Monitor 2018
https://www.transperth.wa.gov.au/About/Surveys-Statistics/Passenger-Surveys See page 4, they spell it out ' What We've Done ' in terms of sampling, surveys, numbers, significance testing and so. This sort of information has never been forthcoming from TransLink (Surprised? Nope .. ).
A particular point with the TransLink monthly snapshots is accessibility KPI. Talking to representatives of the PWD community they don't seem to be ever asked. If you want to find out the impacts of lift outages etc. you don't ask able bodied passengers. The lift outage problem is so bad I have set up a special link for people to check before they travel (see

http://seqliftsout.info/I am thinking of putting in a RTI for how the monthly snapshot KPIs are actually determined. Survey questions, sample sizes, significance testing, with particular reference to the accessibility and affordability KPIs.
