Try what you as ref consider to be advantage 40 yards out, signal it, shout it, it looks good, but for some reason, it does not pay off (remember it wont always actually end up in the net, through no fault of your own), then no marks are lost.
Try one...blah blah blah..and its the only goal of the game....then, (clearly bearing in mind the other aspects of the game), then, you have the possibility of a higher mark based on your management of the game
By all mean, do 4/5 and they are at best dubious then you are risking mark deduction.
You cannot base the marking down of dissent on this..the referee could make a wrong PK call and lead to dissent, its the call itself you would mark down for, not the dissent which follows. The players control their dissent, you control your match decisions.
Then again, prev posts by Obi suggest, he has little respect for the players on the park, it might just pass him by that majority of grass roots play for enjoyment, and are well aware of their limited ability.
Also, by posting as he does re what he considers acceptable, you run the huge risk of a referee changing his natural game to suit the observer in question. What you end up seeing then is a referee officiating as he thinks the assessor would like to see, and this is pure pants, what any observer actually does want to see is that referee, his personality, his control, his confidence and his ability.
