I guess I am looking for accuracy and consistency, I have been checking several boats that I am considering and almost all of them the difference in the numbers is off by very little (example: 0.02 or so) when I found a big difference with Com-Pac a warning light went off. When you start using things like “reported” I have to ask reported by whom? From my understanding the Com-Pac 23’s generally reflect more of the 16.90 from what I have been reading, which is fine for my use but a person could be very disappointed if you didn’t check it out by reading from multiple sources. It’s ok, I created an easy to use formula to check, it now takes me longer to find the boat spec’s than it does to run the formula. Thank you for looking at this, I completely missed the S.A (reported).
