You crack me up.
It is hard to tell if the center part lays (or is it lies?) flat before you put the border on. If it does, then the center-measure method should work fine. If it doesn't, you could adjust or tame the "offending" bias triangles so the center DOES behave. I am in a similar situation with a Lone Star center - it has a slight wave in it and I know that it will not be flat. (So it is in a box until my patience returns.)
