After compiling all the information for the region, a couple of things have lept out at me.
35 Different drivers have taken part.

Only 11 Drivers have completed 2 rounds in 4WD

and
7 in 2WD

Also means that I now have the accounts in order and am about to go shopping for more silverware. Categories include: -

2nd place in 4WD after 2 rounds.
Highest placed CF tub chassis.
Most worthy driver, as voted by the above three winners etc.
Other suggestions include: -

Although, this will require another surge of entries.
