I’m not an expert at this but I would say that Strikers, with a GD of +43, have been playing lower ranked teams than Beach (GD +24). Plus you are talking about a YS score of .18 between Beach and Strikers which is negligible. It’s all about your opponent’s strength (YS score) along with goal differential. I’m probably over simplifying it. If also means that Strikers and Beach should be playing up at Flight 1 (IMO).
That would explain the difference between Beach and Strikers (both flt 2), but not why 17 of the 19 B04 flt 1 teams in SCDSL all ranked below two flt 2 teams.
