Don’t count tournaments that they happened to both be playing at - just count non league games played between clubs.
This is imprecise. I'm excluding weekends where there is more than 1 game in a day, obvious holidays, and weekends where more than 2 games are played. I included the team and a date they played that didn't trigger any of the exclusions. In several cases there is more than one non-tourney game between the orgs but I'm not hunting them all down:
Blazers (PWAA 10/14 @NE Skatezone)
Central Penn (SQ A National 9/16 @Regency)
CCSC (PWA National 10/29 @CCSC)
Delco (BTM A American 10/14 @Delco)
Ducks (16U A National 9/30 @IceLine)
Haverford (PWB Orange 10/20)
Ice Dogs (16U A American 11/3 @Hatfield)
JBH (U16 A American 11/10 @UD)
Lancaster (BTM A National 9/14 @IceLine)
OYR (U15AA 10/28 @OYR)
Palmyra (BTM AA 10/13 @Palmyra)
Snider (BTM A American 2/24/19 @Class of 1923)
Valley Forge (BTM A American 12/9 @Ice Line)
Warwick (BTM A National 11/17 @IceLine)
York (BTM A National 10/21 @IceLine)
Admittedly the list is smaller but it's still pretty long.
