Brandy, i can see where your coming from mate, however, a 90 is a 90.
This is not a thread to resolve projects that have been undertaken or about to be taken on.
This is just a consensus of things when we were a lot younger, trying to fathom out the intricasies of scaffolding, in the days before we needed a design to put up a scaffold on a job.
Just a bit of a laugh really mate, however, at the same time, still a learning curve, I myself plus many others in the game, Still learn, and very happy to learn also.
Good post Brandy mate.
