I think it’s a good product and I’ve been using it to watch my recent flights. I’ve noticed a couple issues that you’re probably aware of:
route- the route show is the route I filed rather than the route actually flown. (Yesterday my route changed before takeoff from the filed route but the filed route was shown in the history).
altitude-the altitude shown in the track log isn’t accurate. Yesterday my altitude never exceeded fl200 but fl220 is shown in the track log. (The controller asked me if I could accept fl220 and was going to give it to me but apparently couldn’t because the next sector wouldn’t take it.)
