I think this question is easier to answer than many others (not easy, just easier).
If eventually a full narrative, in some kind of rational order, is found in the plants, where the individual plants relate well to the whole, then evaluating it will not be as troublesome as individual IDs with no relation to what is around them.
Right now it's guesswork, but the pieces might fall into some kind of order with a bit of time and effort. If there's something there, there's a chance of finding it.
