I just realized you have some wrong numbers for Polish SoS by your reddit post, I think you should double check them (there was just 1 GHost Fenn in that cut for example)
Anyway, your data seems to confirm that we have one of the most diverse meta ever: in 2016 45% of the meta was Palpaces and Jumps, in 2017 we had token stacking madness taking 40% of the meta, with Parattanni and Defenders taking the largest part (and the 5% of Ghost Biggs could be argued is just another kind of token stacking, at least the one without Finn definetely was).
Right now the 45% is taken by much more different archetypes (and which the #1 taking a far smaller portion of the meta compared by previous #1):
-Ghost Fenn
-Palpaces
-Dash+
-Nymranda
-Rey+
Are all lists that play quite differently from one another, the most similars are probably Ghost Fenn and Dash+/Rey+ (and those 2 are also different from each other)
And yeah, old Palpatine was one of the dumbest thing ever designed for xwing. I'm glad that level or certainty is gone
