Anyone measuring force required to remove completed items?

I'm just curious if anyone's measured how much lateral force is required to dislodge a printed item from the print bed?
I'm sure it's different for different materials, but I'm wondering if it's within the power of the Y-axis if a fence were added on the extruder. IE: On completion, move Y-axis to one side, lower head, move Y back across to knock object off with the extruder (and presumably off the table and out the bottom of Mendel).

I think you would need a moving fence that rotates around a horizontal pin, so when the object is pushed against it, the fence returns a lifting force to peel the object

With a rigid bed, large objects are too hard to pull off by hand. They need a knife under a corner to start them peeling. Smaller objects can be knocked off with a sharp tap from a hammer. I don't the y-axis would be able to knock objects off in general.

That is why I made a flexible bed for easy manual release and am working on film held down by vacuum for automatic release.
