The recommendation to add an increment comes from, amongst others, the IFALPA Working Group on CFIT, and if you don't add the increment, you're breaking the law when you sink below MDA in the go-around.
To my knowledge, Jeppesen plates do not have this increment added, contrary to information above. My company uses Jepps, and we add an increment to all non-precision minima except circling minima, provided the intention is to level at or above the circling minima to maneouvre.
