I like how you say 6th partial is "tending sharp" and 7th partial is "tending flat", like they're comparable. I don't know about your horn, but on every one I've played that 6th partial is pretty close but the 7th partial is so far out that we refer to positions on the 7th as half positions. Euphoniums don't even play the 7th partial because it's so far off. They'll play the F# and G from 8th partial.

(Didn't mean to imply you didn't know that, I just was humored by you using the same term for both).
