Your map grid system is chafing my legs

You saying something does not in any way automatically make it true. Quit talking as though your opinion is fact and then perhaps people will be less harsh towards you on the matter.

In this case, I am not stating an opinion, I am stating a fact.

Letter number leaves no room for ambiguity or confusion. They are not the same character set, thus, they are not confused.

You can reverse them, etc, and no matter what, the end result is the same. Whether I type (A,1) or (1,A) on the map you find A whether its on the X or Y axis doesnt matter. You just find the axis that corresponds to that. Then you find 1. One and done. No confusion. No ambiguity.
