Every grind and flip you'll grind out a bit more of any distortion. For majorly warped stuff it's best to do shimming for the first step then flip back and forth until flat. 3 points would work fine on something that's stiff but won't do any good on something that flexes a lot under its own weight. Those types of parts can get tricky.
