Duplicating objects through particle hair very uneven

I’ve been trying to place some objects on a UV sphere (the vertices and faces are laid fairly evenly),
but I get vert uneven results.
As you can see in the screenshots the ‘even distribution is on’

Am I missing something or is it a bug?

Make it emit from “Verts”

@Iceangel
That makes absolutely no difference (in terms of evenness or otherwise), and preempting your next post neither does setting it to volume.
