Yes, the data is that consistent. It has been a while since a new recovery item was added to the game. If you can find a recovery item that isn't in the data file, please tell me and I'll add it.
There might be a new recovery item with the sandworm. I haven't fully checked that yet. The last new recovery item I added was the high-pressure seltzer bottle dropped by clownfish.
Fair enough. Just please let us clueless ones know when we need to change it out, instead of just the script itself.
