There’ll always have to be a threshold though. If everything goes up as no try until proven otherwise, needing clear evidence as an absolute threshold, then there’ll be outrage when tries that are nearly-certainly tries are chalked off. So… balance of probabilities? Which is a guess.
There’s as strong a case as sending everything up as a try unless proven otherwise - it’s just a question who would get the benefit of the doubt.
My guess about Burgess’s try is probably similar to yours, but it is a guess.
