I finally asked SK the official rule for this seat.
They said 1.5" shell clearance RF.
It is conservative because of the fabric cushion at the top, they did note.
So I don't know if that answered any questions, lol.
I think I'll go by 1.5" inch but my real reason might be b/c my toddler might outgrow his Advocate and NEED that seat before my daughter maxes out anyway. He is huge and she is more average.
