The newspaper article said 19 graduates as at April 2019. So if they are up to 50 now then they have completed an additional 30 students in 9 months. Not many given they have had over 400 students this year.
The article also said that only 2 of the 19 were novices (ie; had started from scratch.) I wonder how many of the 50 have gone all the way with Soar.
I would be even more interested to know how many of the 59 have a job in aviation.
