So then non-tracking would not only be frustrating like you said but also produce a crappy image.
The calculation is not correct. The sun moves 15 degrees per hour, so it moves 15 arc minutes per minute of time, hence 15 arc seconds per second of time. So in 1/60 sec it moves 15/60=0.25 arc seconds
