If you switch from a pot-raise to a minraise, but raise the same number of hands, and he calls with the same number of hands that he's calling with before, then you generate smaller pots while in position, with the same hand mix. So that's a net negative for you.

You save money when he reraises you and you choose to fold, but that's a lot less common than him flatcalling your raise.
