I admit I had to brute-force for the two acronyms... but yay :)
Although, on another site that I go to, some people would consider 16A - 18A to be a "bung" because the same letter position changes twice - basically, if you can remove one word from the ladder and have the result still be a valid ladder, it's something best avoided (although I realize that the grid cannot be edited once it's published, so there is no easy fix).
