You described whoops, not stutters, which are allowed as you said are two or more rounded obstacles with max height 0.6m with a minimum distance of crests of 3m & maximum of 6m ie you can have 3 rounded obstacless in a whoop. Stutters are two or more obstacles with max height 1.0m with a minimum distance of peaks of 1m & maximum of 3m.
Other deffinitions
A table top is a jump with a flat surface, min length 3m, max 18m (Already stated but it leads into the next one)
Multiple jumps (Doubles) An obstacle consisting of 2 to a max of 4 "jumps" within 10 metres of the preceding "jump" on a straight section of the course. It is not necessary to deem that the "jumps" may be able to be jumped singly or as a set. (10m from take off points or from landing to take off?)
With the bridges apart from the engineers report they must have suitable barriers in place to prevent machines, riders & debris from falling onto the track surface below.

PS Bacchuss Marsh went black a couple of years ago but an anomaly means you can have MAV sanctioned coaching course etc. there but not race.
