Sorry for starting a new post, but I seem to get better replies if I do so off a topic that I clicked "Correct".
Anyhow this is based off my previous post "Check distance (within a range) moved in y-axis?".
What I realisied was that I would be doing this in a Responsive Scaling animation and that throws out all the distances.
Here's the latest version file: http://twistedpancreas.com/edge/misc/yAxisScaled.zip
Is there a way around that?
Thanks in advance (and sorry 
).
