What is the difference between 16 yard trap and olympic trap?

in 16 yard trap, one stands at 1 of 5 posts and shoots clay pigeons from only one thrower and the line on which you stand is an arc shape. in Olympic trap there are still 5 posts but they are in a straight line. also there are 15 throwers. 3 throwers per shooter. each shooter will receive 5 targets per post. two left targets, two right targets and a straightaway, not knowing in what order. you also may fire two shots at a single target. the Olympic targets are much faster
