I watched this meeting as a neutral observer whilst on holiday in the area. I have seen many meetings a Wimborne Road over the past 30 years and I have been a speedway fan for over 60 years.
Firstly, in my opinion, there is nothing wrong with the shape of the track although the racing surface could be improved. Prior to the first heat I noticed that on the first bend there was virtually no shale on the inside section with the dirt "heaped" along the perimeter. This was probably to accommodate the home riders who prefer the track prepared in this way. There is nothing wrong with this home advantage procedure - it is the same technique at most tracks.
Secondly, the track grading appears to be inadequate. The "tiny" blade used hardly touches the track surface - a proper revolving grader should be used to eliminate any ruts. Len Silver could advise on the use of this type of grader and track preparation in general!!
A few years ago I did see the famous "hole" on the entry to the first bend which seemed to appear after a few races. I thought that this had been resolved until I saw Tom Brennan hit the hole/ridge and take off into the fence. Proper track grading should have eliminated any such ruts or waves.
It was evident after the first four heats that the away team were not using correct gearing or "set-ups" and were consistently out-gated. Apart from the machinery the Poole riders were certainly up for this contest and had a winning mentality. Overall, the performance of the away riders was disappointing. I was impressed with the tenacious riding of Lee Complin last year at Poole when he was riding for Newcastle but he seemed to be a shadow of the rider I saw last year. It did occur to me that he had some machine problems which may have contributed to his poor performance but this is only conjecture on my part.
