Typical self-impressed smugness. You MUST accept the 10 foot target hidden height in the 2nd image example in my longish reply to FreedomLover2020 or you are nothing more than a banging gong distraction.

Edit: since you worded you reply as a question, I'll humbly take back my response (and even ask forgiveness for making wrong assumptions) if you are serious about looking into the realistic points. People like me deal mostly with nothing but closed minded smugness from people who have no idea what they don't know, so my response is likely a reflex action by now.
