A few?, surely you jest?.

Your 'few' is near 20 drivers (if you can round down 15+, I can round up a few), and lets put that into perspective for a second...

This is "Brendale", the original nitro core of Queensland on-road racing, I think I can safely say the vast majority of members own at least one fuel powered rc car.
So yeah, with any even remotely 'fair' spread of points, nitro 'will' dominate at Brendale, because it's predominantly a nitro track, with most members running something that runs on liquid fuel.

Saying it's unfair for Brendale to win it's own meet based on nitro numbers, is like saying any other club is not able to win, based on what is popular being run at their own track.

We are looking at a part reversal of a system that seemed stacked in electric favor, yeah it's going to run in favor of nitro at Brendale, but it's not fair to try and shoot down the system based on that, I'd have posted numbers from other rounds, but I could not find them.

End of the day, clubs like Logan who can bring big numbers will likely still win overall, just maybe not quite as easily as previously if they don't have the nitro numbers at some tracks, you say more nitro guys should go electric, well the same is just as true the other way round, if you don't want a white wash of nitro come March, get more of the electric guys into Gas and Pro.
