BrepInc not detecting

I am running an array of points along the y axis in steps with hoopsnake and a simple move.

I want the points to behave a bit like wind / particles e.g. deflect + grow when they hit the object.

Trying to use BrepInc to see when the points enter the brep is not working.

Am I using hoopsnake or BrepInc wrongly?

Tried a whole bunch of reconfiguring, some of these points seem obviously inside the brep to me... but nothing shows as True on the BrepInc output.
