This is my very first comment on this forum.
In response to starting procedures, I too get fed up with restarts & remember only too well all the 'Mauger' rolling starts, however after watching some old footage showing movement at the tapes I really enjoyed the tactics.
It appears that nowadays all riders MUST leave the gate at the same time & a rider , even though he does not move when the tapes go up is penalized, surely if you are clever enough to anticipate the tape release you should be allowed to continue !
I think that if there was another chalked line behind the start line, ie. a bike length, once in, riders should not be allowed to leave their gate position, this would obviate the 'gardening' & providing they do not touch the tapes, they can move back & forth a little as much as they dare.
