The Mussile 1:01pm 1:01pm, 10 Jul 2025 1,206 posts	Quote Pin The Mussile Somerdales distance can vary wildly due to the hexagoning effect of GPS so I have to regularly answer questions on it. Some people seem to think a digital readout is 100% accurate regardless
Meep Meep 5:11pm 5:11pm, 10 Jul 2025 247 posts	Quote Pin Meep Meep I remember my physics teacher saying that to us about 30 years ago. With digital readouts becoming more and more common my teacher said "people think since a digital readout means something is 100% accurate". Then we got taught how to read vernier scales, which I definitely remember to this day. Honest.

It’s probably the same as running around a running track (if you don’t have a fancy track mode). Try it wearing one watch on your left arm and one on the right arm and compare the difference - you’ll get very different measurements!
