How accurate is the don't get along at all comment

Found it in a few of my bought horses, one of whom just won with the same jockey. Just wondered whether I should switch them or keep it as is?

All jockey comments are increasingly more accurate the better that particular jockey knows the horse. I typically don’t trust anything they say until that jockey has said “I know X like the back of my hand” which is the maximum understanding between jockey & horse. Up until that point, jockeys are mostly just saying jibberish IMO. Even after that point, they can make an occasional mistake, so I’d look for the jockey to say they don’t get along more than once (and without many “we get along great!” type comments in there, too).
