So. Too tight? And how do I solve it.
ISO sq taper.
FWIW, trialled 111 (record Pista) and 115.5 (Chorus), pictured.

Too tight?

Ride it and see. Frame stiffness and to some extent riding style will determine whether the crank and chainstay bend enough to meet in the middle

And how do I solve it

Hammer the chainstay or file the crank 😃
