So is it a higher value makes it less sensitive?
I think the conf file documentation needs improving.

I'm not certain either and agree that clarification is needed, but I always
assumed it was to set the percent of change that gets ignored. If you set
it to 10 and >10% of the image changed in a single frame it would be
ignored. Set it to 80 and 80% needs to change in a single frame.

The wiki page is here:
http://www.lavrsen.dk/foswiki/bin/view/Motion/ConfigOptionLightswitch
People are free to improve the wording & explanation there, it's a wiki :)
I would have thought there's probably at least a small range of values that
would work for most people that should probably be suggested in the wiki page
(eg. I'm pretty certain you'd only very rarely set it below say 40%, though
I've never experimented with it so don't know how true that it).
Cheers,
Joseph
