this issue comes up from time to time. there are ways of estimating recline angle, a common one being to hold a piece of paper horizontally with your car on level ground, and just eyeballing the recline angle of the seat.
what i've been playing around with lately is something that seems to give reliable numbers. i take a picture of a carseat and open it in my CAD (computer-aided-design) software. then i draw a line along the side of the shell. the software spits back the angle of the line.
for this to work optimally, the pictures should be at or near a perfect straight-on profile shot of the carseat, shot at the same height as the carseat from an open rear passenger door, with the camera and car both level. the scale or size of the pic is not important.
i did this the other day for someone here, and used two photos taken from either side of the carseat. the pics weren't perfect, and the software still spit out numbers for each pic that were within 2 degrees of each other, so i think the method is pretty reliable, and probably near perfect if the pics are straight and level.
if anyone wants to get an estimate of their recline angle this way, just post a pic (or two or three, the more the better) here in this thread and i will post back with a picture of the line drawn through the seat and the calculated angle.
