I can't even find a link to the Short Notice Cancellations page on their website. Using a general internet search engine finds
a page, but it looks like it hasn't been updated since May which is no use.
I'm going to make a table of timetabled journeys vs journeys which ran. Can someone confirm the peak daily vehicle requirement ("PVR") for the 20 and 63? I believe the 68 has a PVR of one.
Edit at about 1710hrs:
I did type up the below but thinking about it my method of recording journeys is too imprecise so it can't really be used.
I've done a very brief table and it looks like Monday to Saturday from the 17th to the 29th of June, the 20/63/68 all met their daily PVR at least once on 74% of days. That is more than I was expecting but is limited by the fact that I was counting unique vehicles over the whole day per route, so doesn't guarantee that every journey was operated.
A day that stands out is Saturday the 22nd: none of the three routes met their PVR on that day.
the 20 had one vehicle (0426 - SN14 FFZ) operating from the ~0630 departure until the ~0900 departure, but no vehicles after that.
the 63 then had the same vehicle operating departures from ~1130 until ~1330, but no vehicles after that.
the 68 had no vehicles all day.
Because no route had departures covering the whole day, I've recorded them as zero meaning the sheet calculated 0% of the journeys running.
