Just to fill everyone in on where I am coming from, I like John Collins, hail from an era of non stop rules and I can even remember when a 2 was introduced to much shaking of heads !
Now however ani domini has stopped my riding, or should I say passengering - Yes as a sidecar competitor I never had any trouble defining a stop as it usually meant you were stuck and not making any forward progress !
I now observe for my club in the SE - probably 4 times a year and each time before I do, I now have to get someone to talk me through just what I am meant to be doing ( we run 22A and 22B events )
Recently my club ran an open trial under 22A but it was not the stopping decision I had a problem with as a non riding observor. My problem came when some competitors chose to put the front brake on, depress the forks and swing the back around to negogiate a tight turn which, other conpetitors had managed to ride round.
22A(d) " The rider intentionally moves either wheel to the side without forward motion " - so that really should be a 5 but I had riders query this and want a 1.
This sort of skill was introduced several years ago when bunny hopping first came in and reading the rules of both 22A and 22B now, I can't see anywhere where this is allowed - which I think is a shame.
To sign off from a non riding obersorver's point of view I don't have a problem with a stop being a 1 or 5 where I do have a problem is 22A (d) and thats where I think something needs to be clarified.
