You brag about your abilities, but the bores have nothing to do with those. Each horn is different on so many levels, that you can't pinpoint the bore as being the thing that gives the horn the characteristic it has. There are so many more important factors as discussed earlier in the thread. Weighted MPs aren't wrong, they are just another tool to use. Range doesn't prove that a setup is wrong. I hope i understood your post correctly...it is so jumbled it is hard to decipher.
