Wishgranter, thanks, I am relieved now! 
How exactly does this weight work then.
Is it relative between the different CPs or is it absolute in relation to tie points?
Can you describe a scenario with a couple different settings and what this changes?
Thanks for the video, martinb!
As I see it, you really only use the CPs as helpers since you don’t spend ages placing them.
Or is that just my lack in experience?
Is it correct to assume then, that they do not have a higher priority than tie points?
What I am aiming at is: can falsely placed CPs screw up the automatic alignment?
