The letter columns are different on each of the maps. The SAT map has the letters one grid space higher. It may cause confusion if someone is looking at a different map when communicating. Also there is no "8" on the SAT map, but there is on the MGRS map. That may not be as much of an issue... but if you're adjusting maps...

Thanks for the heads up, sadly won't be able to edit them to match.
