Incidentally there is no node whose name suggests anything meaningful as regards incremental or absolute arcs, which makes me wonder if its in the file as a default at all until someone changes it, then gets saved as a preference. Maybe the default setting is whatever happens to be in memory at the time the program is first loaded?
Probably clock speed which is why it varies.

When the program is down loaded it defaults to absolute, why I have no idea given that most people use incremental but this is why there is all the confusion over what has been dubbed 'crop circles'

However if you change your post processor to have G91.1 in the startup line, every post you make will force the program to default to incremental and you never see crop circles.
