The first one looks OK as requested position and reported position match, but in the second one the reported position is listed as invalid. You can't really tell from a static shot - you need to watch the two figures as you rev the engine up and down - they should follow each other closely, and the reported position should stay steady if you hold the revs steady.

Yes, dynamic data is always more useful than static!
