It is more complicated. An old TV set is not sharp. Its dithering mask 
work as a sort of anti-aliasing filter. The same applies to the live 
images, which perception is different from artificial images. E.g. 
running curves on a high-resolution screen without anti-aliasing appear 
jerking even at 20ms rate. Furthermore, jitter around 10ms is visible 
too. So, I understand how 80ms might become a problem.
