Zero Feels

Ive found that the first Y coordinate is basically exactly or close to what grid theyre in, and the 2nd is opposite since the bottom grid starts at the highest number and goes top to bottom from 0. So the farthest grid down is 152, so you take 152 and subtract the first 2-3 numbers (1000 is 2 numbers 10000 is 3) and you have within a grid of where they are. So 2525.xx, 8245.xx = somewhere at 025 070.
