sorry I thought that would be self obvious? Quickload suffers in the same way as even if you measure the water volume of the case ,the chamber is still an unknown, I personally think some people overthink the whole thing and that for them the purpose of the exercise is theoretical results as opposed to real life results, that said, there is nothing wrong with that approach if its what rocks your boat.
