Overexposing colour negative

Petapixel has Daniel Lachman tell us how much you can over expose colour negative film:

“What I took away from this is that film basically can’t be overexposed, it can just be too dense for the scanner to be able to shoot through the negative. But the information will always be there.”

My quick take is that you can shoot it at +2 and it will be more tolerant to under exposure error.
