Tinder might state “8 miles”, which on its own looks of small use to you. However could subsequently starting shuffling north, pixel-by-pixel, with each action asking Tinder once more what lengths away your own target are. “8 miles” it may say. “8 miles, 8 miles, 8 kilometers, 8 miles, 7 miles.” In the event your assumptions about Tinder’s approximation techniques become correct, then your aim at which they flips from responding with “8 kilometers” to “7 miles” is the point at which the target is exactly 7.5 kilometers aside.
