in this building, i used to live in suite 1411, on the 14th floor which is actually the 13th floor, so 1411 is actually 1311 and like units, e.g. 1511 is actually 1411 and 1611 is actually 1511, etcetera etcetera; and my current unit which is 2209 is actually 2109 and the other like units, e.g. 2309 is actually 2209, which is my current unit although it's not really.🤣
likewise, there is a mathematician that I once heard that argues that the "B" should be floor "-1". Also start with the ground floor being zero, so you would have been on the 12th floor. An interesting idea.
