Alaia Concave?

Im planning on shaping my Alaia starting tomorrow morning, and I was wondering how far up the concave goes on the belly of the board. Does it go all the way through or just half way up the belly? And usually how wide is the concave on most Alaia’s? The tail width is going to be 16" and the widest part of the board is going to be 19". And also 5’7" tall

Let your imagination run wild
