Let's say you are given a set of numbers, called the state, and you are supposed to use external information to estimate if they are correct.
I am looking for a word that means "to estimate the quality/correctness of something". I don't want to use "evaluate" because, in the context of numbers, it typically has another meaning, and "judge" seems too informal to me. "Verify" and "validate" would fit, but imply to much confidence in the result.
I want to say something like "I have ??? the state; it is correct" or "...; there might be a problem with X".
So far, my search turned up "assess" and "assay", but I don't know which would be better in this context.
