Glad you like them, Mattrom, though Cox & Rathvon used to pose much better & harder puzzles when they worked for The Atlantic. That went south some years ago when the magazine restricted the puzzle to on-line subscribers, then dropped it completely.
Stupid decision - I stopped reading it. How many others?
Americanisms are to be expected, as are British-isms (?) in the puzzles we love.
I have an archived list of Atlantic puzzle links which I probably posted some time ago, but will have to check if they still work. If so, I'll post them again.
Cheers.
