I just read through the posts above and it looks like your looking for an answer that doesn't exist.
The problem here is that we as a paintball community do not have a standardised set of rules and in my opinion often ignore the wealth of experience that can be found in the more established and developed rule books.
I know there are moves to standardise the UK's tournament rulebooks and personally I can't wait for this to happen. I just hope that a great deal of attention is paid to the international series rules such as the Millennium Series when this is done. When the rules are standardised you may be able to get a definitive answer but until then you are going to continually find poor rules that are inappropriately interpreted.
The reason there is concern about trigger bounce is that it can cause artificially high rates of fire that exceed the ‘one shot one pull rule’. Right now the rules are trying to keep up with the technology used in the markers. With my marshals hat on I would be alerted by any marker that I believe is firing shots in excess of the number of times the trigger is pulled. If I then take the gun and squeeze the trigger resulting in burst fire the gun is illegal. I would apply common sense and have to feel that this could easily be repeated in a game. I would then consult with the field ultimate and in turn tournament ultimate and if it was deliberately set up, according to Millennium rules, would result in a player ban. A marshal is incorrect if he uses an implausible method to make the trigger bounce i.e. a method that the player could not use in a game.
More complicated methods can be used to test if a marker has a cheat on it to make it fire faster than one shot one pull. The most developed rules in this case are the X-Ball Nations Cup amended rules that come straight from the NXL, they describe a set of test procedures that can be used by a ref to see if the gun has a cheat, they would also find trigger bounce. Maybe you guys should check them out on the Millennium Web site. Of course they don't apply to domestic tournaments but do give an idea of the problems with electros.
In the mean time the most important thing is to make sure you don't set your trigger too short and sensitive. Generally you aren’t going to have real problems with trigger bounce unless 'you' set the gun up that way.
Toma in particular you need to check out some tourney rules! No offence dude, but you’ve got the wrong end of the stick. Got to
www.millennium-series.com the rules there should give you the background you need.
I hope this helps,
