See, that's what i mean... both the two posts above are reasonable... it's accepted to sit pre position for rangefinding, but it might raise an eye if you did something else... neither are covered in the rules.
So if you want positions checked there's going to have to be at least a definition of when they are checked that needs to be made... Simon's camera work showing 4-5 dubious kneelers at Tawd is all very well, but it can't be said that they were illegal because it's not 100% clear, and we don't know the shot was taken in that position. For all we know, the person could have moved their position then taken the shot.
Just showing why we need to have marshalls and why for that to happen we need volunteers to step forward and give their time up. Else otherwise we'll be here all year
