Unless you're good enough to build a bridge that holds exactly 15.0 kg and no more, you're overbuilding the bridge when it holds all the weight. Because the bridge can hold more then, but you can't load it that much.
And there's nothing different about having a 10 gram bridge that holds 15 kg or a 5 gram bridge that holds 7.5 kg. The efficiency is the same.
I never built my bridges to hold the entire weight, because that's overbuilding and not getting the maximum efficiency possible out of the bridge.
I like to walk home from competition with a bridge that is in a million pieces.
in my opinion heavier bridges have naturaly higher efficiencies, if weight was the only variable, if a 10g bridge would hold 15kg and 5g bridge would hold less than 7. i'm probably wrong, but i still would like my bridges to hold all the weight. It's less nerve racking for me. Now having that said, this year, not one of my bridges survived all the weight to tell the tale.

I wasn't able to see it, but maybe you could try emailing the coach to see if he would be willing to share the info.

like andrewwski said, if you hold all the weight, 99.99% chance that you could of held more than 15 kg, which would mean your efficency would be lower than if your very super light bridge broke.

Haha, after watching this thread grow to an amazing length, my new prediction for the national bridge competition is this: the number of posts on this thread will be the efficiency needed to be in the top 8 for either division.
: D
In all honestly, even though that was a joke, the number probably won't be too far off.

I'm guessing that if you score over 2000, then you're probably in the top 5. I think that 1500 will be the top 20 teams.

No way. I think 1500 makes you top 12, probably top 10, maybe even in the medals. People have been really really not that good at bridges...
I agree with Aia's analysis. Funny coincidence!

Yeah, you're probably right. But I have no doubt that a 2000+ efficiency will be top 3, maybe even top 2.

Would top 1700 efficiency make you medal or place in the top 6?

For B division, I'd definitely say that's top ten. I have a really hard time predicting what will be the threshold for medaling in either division for Elevated Bridge. There have been high scores this season, but many of these high scores have been from schools that didn't advance to Nationals.
I also have to wonder if the Georgia humidity will drop the bridge scores down. Any guesses on that one?
