I can only guess at your motivation for sticking to obscure internet forums instead of bringing your Earth-shattering evidence and scientific prowess
That's the bizarre thing...none of what I'm discussing in this thread is *earth shattering*, nor does it require significant *scientific prowess*.
Determining initial tilt is pretty darn simple really, though the techniques employed do have a slight learning-curve I suppose.
These are basic observational details, and the kind of thing that should have been done years ago, and certainly not requiring a few essentially anonymous researchers on a back-water forum to have to repeatedly explain to folk who repeatedly boast about how superior they are.
I don't know how many people telling you that you don't know what you are talking about it would take you to start saying, "hmmmm maybe they're on to something", but I'm beginning to suspect that may be the reason you aren't on the university lecture circuit or publishing in respected scientific journals right now
To be honest, it's things like you've just said that are part of the issue here. The details being presented are not complicated or difficult to replicate yourself. I think it's simply that you *trust* the (frankly increasingly bizarre) viewpoint of folk like tfk that tends to indicate that a) you personally don't understand how simple it really is, and b) prefer to therefore side yourself with the *opposing* viewpoint without critically asessing exactly what is on the table.
To be in the position of providing/explaining sub-pixel position change trace data and techniques which allow simple and accurate specification of various metrics in a way that
can easily be replicated and confirmed by anyone willing to perform what is (in my view) a pretty simple process...and yet receiving complaints, accusations of deliberate distortion and clearly incorrect *counter claims* from folk either unwilling to replicate the data or using techniques such as *memorising the position of a dot, opening the next file and seeing what has changed*...is mind boggling. There's just no excuse in my opinion.
I personally put all the resources and data I generate online so I think it's pretty clear there's no *distortion*, *lying*, (list of inappropriate terms of your choice here). Nonsense hand-waving from others is just that, nonsense.
Initial tilt determination...It's not rocket science, and it's not earth shattering either.
It's about 1 degree.
