I thought it happened in 2014…But I admittedly do not track such stats.
EDIT: Not 2014, duh…2016?
Sorry,
@dunkej01 , I think my memory is faltering. I think PSU did it as recently as 2019. Based on the press releases, PSU appeared to lead after (or near the conclusion of) every session:
Session I: PSU 21.0, OhSt 15.5
Session II*: PSU 32.5, OhSt 25.0
Session III: PSU 80.0, OhSt 66.5
Session IV: PSU 120.5, OhSt 88.5
Session V*^: PSU 123.5, OhSt 95.5
Session VI: PSU 137.5, OhSt 96.5
* “Near the end of session”
^ PSU clinched title as of the writing
So much winning, much to lose track of. 😁
