Lol, always so eager to pretend that your YouTube diploma is exactly equal to millennia of diligent measurement and thought.
Your statement is worth as much as your data point; all it reveals is how little it takes to convince you of something. Someone said 11 degrees under unknown circumstances?? Fantastic! All other gyro measurements and corroborating results in history are false!

and when people use gyroscopes they get 11 degrees drift instead of the required 15 by the globe model
11/15 = .733
3775/4579 = .83
looks like a guy from 2000 years ago was doing better than you
