No, I understood it perfectly and I am well aware of why you used it.
but yes this really is your schtick "In common usage, the word shtick has also come to mean any talent, style, habit, or other eccentricity for which a person is particularly well-known, even if not intended for comedic purposes. For example, a person who is known locally for his or her ability to eat dozens of hot dogs quickly might say that it was their shtick". I do believe you misunderstood the context I was using it in which is fine.
In older posts I also talked about it being centered between the two wheels, but even if I hadn't, it should be obvious to anyone who knows how a long-john looks. It is also funny how you thank me for restating that factoid, yet - as is evident earlier on in your post - you're still not acknowledging it.
And thanks for answering about where the gravity is centered, is actually centered and how so, makes a lot more sense than older iterations I've seen.
