Thank you for the explanation. That clears things up.

Ok. I will set --sieve2width 3 --sieve2height 3 --sieve1size %p and
keep p at something like 2 or 3.

However I would still *like* to have my original wish: "Keep only the
best ten control points", somehow magically balancing quality and
distribution.

I am quite happy with current single control for this setting, it
just should work.

thanks for your assistance.

Title:
  cpfind - add option to limit number of control points

Status in Hugin - Panorama Tools GUI:
  Triaged

Bug description:
  cpfind is missing a option to limit the the number of control points per pair of images (like autopano-sift-c's --maxmatches option).

Having a large number of control points (cpfind adds 30+) increases the amount of work to get rid of the bad ones.
