You take your upfront cost + dues until 2042 (You need to estimate this. I use 4.5% increase per year). Take this number and divide by the number of points total you will get in the life of the contract.Not quite sure I understand what you mean that you paid equivalent of $22/pt for a Boardwalk contract, please explain.
I agree on the $130/pt price for BCV. I think the cutoff for BCV/BWV should be about $120/pt given the 2042 expiration, and only then should it be more about convenience than the math.
