Twelve rebus puzzles

How many did I catch? Answer this after you have solved the 12 steps above.

Answer

Sorry for posting this here, but the other location, as a duplicate, is blocked for new answers.

The number caught is:

25

The number missed is:

also 25

The reason is that:

each of the 12 rebus words has an even number of letters, and is a concatenation of the 2 letter US state abbreviations. There are 35 such bigrams, but 10 are duplicates, leaving 25 "caught" and 25 "missed".

Not quite sure of the principle by which some are chosen to be caught. There are other words which could easily be made from the missing ones:

(e.g. FLAK, INKY, INKS, VAIN...).

Thanks for a fun enigma!
