Question about Bertinet's Twisted Cinnamon Buns

Hello,

I just made this recipe from R. Bertinet's which I saw on Youtube and couldn't resist

https://www.foodheavenmag.com/richard-bertinets-twisted-cinnamon-buns/

I'm wondering if it just me or somebody who has made them thinks that the dough has way too much butter and the quantity of the filling is excessive for the size of the dough to cover.

Thanks,
