So...you show a photo where you're in the westernmost car...the one where no one sits because it's a fair walk at Sheppard yonge station.
Also, we don't know when that photo was taken. If it was midday, that would make sense, but we also don't know which direction that train was going. If it was going eastbound in the morning, that can explain the seemingly low ridership. The video I shared was not an outlier. It was taken on a Wednesday afternoon -- the day of lowest weekday ridership and most of the trains were like the one in the video heading towards don mills. Most of the seats were taken on westbound trains as well. There were no Sheppard line delays to account for seemingly high ridership, and none on the Yonge line either. I could not stay to analyze the ridership, but I guarantee it would be better as the day went on since it was a good hour before the afternoon rush started.
Your statement that ridership has declined on the sheppard line over the past 5 years simply has absolutely no merit whatsoever. Here are the statistics.

As you can see, the ridership for every single line with the exception of Line 1 has decreased over this period. Stating one line's ridership is decreasing while the rest of the system's ridership is decreasing is bad statistics and has no merit in any rational argument. Also, these full-line ridership counts are highly dependent on a few things: when the survey is conducted, how many surveyors there are, miscounts, equipment errors, low ridership days, etc. There are too many variables to be able to take these figures with full legitimacy or to spot any sort of trend within them. The surveying occurs in this manner:
1. Days are picked to measure platform traffic at each of the stations: Sheppard Yonge (Sheppard), Bayview, Bessarion, Leslie, Don Mills. Each platform traffic count occurs on a different weekday. Let's say Sheppard Yonge is surveyed during a febuary winter wednesday, Bayview during a may monday, Bessarion on a November Friday, Leslie on a september thursday, and don mills on a December tuesday. Ridership levels vary month by month depending on festivals, subway closures, service levels, and of course, need to go downtown. This example is a little exaggerated, but it is clear that ridership at sheppard yonge and don mills would be grossly understated (when compared to their normal usages), and Bayview Bessarion and Leslie are overstated. This is a bias and it severely affects station counts.
2. When they decide to count individuals, they send people to each subway platform's entrance and exit, and they count the number of people entering the station and exiting the station through turnstiles and bus terminals if I remember correctly. It is very possible for individuals to not be counted or accidentally counted twice during these usage assessments. It is also possible that the counters may take breaks for restrooms, lunches, etc for whatever reason and lose count of individuals.
