Not suggesting who (or anybody) might be in the wrong place, but the two are quite different in how far out over the water one should climb before turning left to join downwind.
My look is that the tracks are per published procedures.
The RED track seems to show
1 - A staight out departure with a teardrop (to the left) turn back to SHM to commence instrument practice(as per the detail of practice instrument training)
2 - What appears to be appears to be two trips around the hold (at about the published distance, which of course is considerably outside the ATZ)
3 - Exiting the hold, on the NDB 20 outbound (with a base turn that is significantly too tight)
4 - Regaining the inbound track to SHM then breaking off to the right for some airwork (all consistent with normal procedures and the AAIB detail)
5 - Airwork to the West
6 - A crosswind rejoin, pretty much along the track line previously used by the RV
7 - One dot beyond the collision point, then a turn to the airport with loss of radar contact halfway there.
The Blue track (the RV) shows
1 - the general handling to the West
2 - A crosswind join over the numbers (i.e. the correct location)
3 - A pattern where the downwind leg looks about 1/2 KM closer to field than that published, but in all other respects consistent with the track.
4 - A departure (the T&G) with a turn commencing 1/2km or less earlier than the track published
5 - A downwind slightly inside of the published track
6 - A loss of track at the collision
All looks pretty much as per published procedures and the circuits seem to be slightly inside the referenced tracks.
