Unless you were there competing or had some inside knowledge you will never get the true story of why. I enjoy your passion for trials, but you seem to come from a time that you never got a failure. (Like the all day dab) That is what was wrong with the rules. Not enough failures and too much time doing nothing. You will have lots more 5`s in no stop!!!
The other problem was course set up for the rules. If they set sections that were ridden under stop and hop, now they are quite harder and could be ridiculously impossible with no-stop.
I scored at Tennessee and we had a rock that was 50/50 on if you made it.(including Bou!) After I returned home I found footage of the same rock from the 2008 event. Most riders made the same rock easily with a stop and perfect set up. Now you have to take what you get on the approach. Totally different riding!
