Was replacing the loosely fitting foam insulation in my half-high basement walls. To get a good tight fit I measured the distance between successive pairs of furring strips, at top and bottom (ie, 4 feet apart), along a roughly 13′ wall:
14-1/16 13-15/16
13-3/4 13-7/8
14-1/4 14-3/8
14-1/4 14-7/8
14-1/4 14-1/4 (even a stopped clock is right twice a day)
14-3/16 14
14-1/2 14-13/16
14-1/4 14
14-5/16 14-3/8
6-5/16 6-1/2
There’s also nearly a two inch variation in wall height (or, more properly, floor depth) from one end of a longer (24-foot) wall to the other. The low spot is in the corner.
If ignorance is bliss why aren’t more people happy?

Have you considered just ripping the foam to a close dimension, within 1/4" or so, and then using spray foam to fill the gaps?
might save a lot of frustration.
Actually, it was a lot easier and less messy to cut to fit. Have to measure anyway, since the measurements are so screwy, and the foam will compress 1/8" or so without much effort.

not sure what the measurements mean...but then I seldom see basements here in Bakersfield. As far as the walls being different in height - maybe the framers were correcting for an out-of-level foundation?
No, if the framers were correcting for out-of-level foundation there wouldn't be that hump in the kitchen floor above.

On a job like that I like to cut my insulation all the same and then put the furring strip up to the insulation.
If I understand this right
I would fit the uncut foam against one furring strip and with the heel of my hand make an impression of the next furring strip onto the back side of the foam panel, then flip it over and cut the foam to the line impression.
I agree. that's the easiest way I found.
