It also makes it the most fair if we are kept in the dark about the track until we have to run it. Every team that either checks the forum or not will be on the exact same page
Exactly this ^. I couldn't have said it better.
Lesson learned from States this weekend - just when you think you'd tested as many surfaces you can anticipate for the track, plywood shows up - would have never guessed this to be a possible surface, and cost us dearly. Others clearly pulled it off, so wasn't impossible by any stretch - just circles back to all the real world comments and advice in this forum to be as prepared as possible for variables in the events.
The plywood got us too. For some reason, the hovercraft stopped in the middle of the track on every run. Strange thing, in Michigan: Our middle school had a 1950g craft, was 5 seconds off of 25, and I know they did a decent job on the test. Yet, they didn't place (top 8). In the past, very few teams were able to get near 25 seconds. Must be really competitive now...

thats funny we got almost no points on the testing portion and somehow ended up fifth xD

Well, if you had states this weekend, and if your track was plywood..... Awww nice! "Others clearly pulled it off" is talking about me!

The Hovercraft track was certainly not ideal. The middle of our track had increased friction as well. We were able to get a 20 second run in, however, and I thought the test was very easy. We ended up getting 3rd in the State - our Hovercraft was 1970g.

maybe if it had been 1999 it would complete the 2/2/2/2 streak

Who knows
We were very prepared for the test, which was too bad because it was certainly the easiest test I have ever taken in Science Olympiad, ever. Basically all we had to do was write Newton's laws, give the unit for energy, and solve for kinetic energy given mass and velocity...

You do realize you can use modeling clay to bring it to max mass during the tournament... -__-

On Avogadro, the written test for hovercraft was in the trial events section. Maybe they just threw the test out for some reason.

I firmly believe that there is an alternate universe where us getting 2nd place instead of 3rd is the difference between our team going to Nationals or not, and in that universe, alternate me and alternate MIScioly get 2nd at Nationals.
