Your estimate of 20% (72 degrees!) is difficult to imagine for a new cartridge, or a used cartridge, or anything other than a completely, utterly and irretrievably trashed-because-it-got-run-over-by-a-truck cartridge. No cantilever would bend anywhere near that far without breaking.
However much it's off, I agree with Thorman. A new cartridge ought to have a cantilever that's within 2-3 degrees of parallel to the body. In percentage terms that's < 1%.
