-The path of the Administrator is beset on all sides by the inequities of the selfish and the tyranny of evil men.

-Nothing\'s gonna get deleted. We\'re gonna be like three little Fonzies here. And what\'s Fonzie like? Come on, what\'s Fonzie like?
-Cool?
-Correctamundo. And that\'s what we\'re gonna be. We\'re gonna be cool. Now, I\'m gonna count to three, and when I count three, you let go of your mouse, and back away from the keyboard. But when you do it, you do it cool. Ready? One... two... three.

Anybody have any ideas for this year's build?
Never argue with an idiot, they will drag you down to their level and then beat you with experience.
Before you criticize a man, walk a mile in his shoes. That way you'll be a mile away and he'll be shoeless.
You should only create problems, that only you know solutions to.

The rules have changed this year, starting with a different lever. It has to have an 80 centimeter rod instead of a meter. When building, make sure to work with your partner, and as always you have to practice! Hope that this helps you out. Just review the new rules, and remember to prepare a binder with Simple Machines things in it! :)

And, as with last year, the rules are still too easy :P

It can be done with minimal modifications from last year, but to accomplish this task QUICKLY is really the challenge.

I'm curious why you think that. We had a really good spread of scores at Nationals last year, and device testing is going to be quite a bit more complicated this year.

Did you have a good spread of scores for the device testing portion? I would imagine that many of the teams with an accurate device were also pretty fast.

It could just be that we had really sucky tests, but the event always seemed very easy (Although I do like the extra difficulty with the lever now).

Agreed that the device testing will be more complicated this year and to accomplish this quickly is proving to be a fantastic challenge. Top ten teams at nats had an average time of 28.35 seconds, but the exam score and accuracy of device cannot be ignored in the determination of their rank. Top 10 teams scored from 44.5-47.3 on the exam portion (out of 50). Top 10 teams had a final score ranging from 91.63-94.66. Ultimately, the margins were extremely narrow- like many of the events at nats.
