I do not know whether the raw scores will be released or not but I placed fourth in the event with ~2320. Hope that helps.

Wow... I have to say, thats quite impressive. MIT is leagues ahead of the invites I have gone to, I have been taking medals with 1500-1700. Thanks for the info.

I messaged the supervisor for the event (he made a spreadsheet of all the test/device scores). He might or might not update soon.

No idea.

If anyone needs to look at the scores urgently, there's a copy on our team website news post.

Stephen Tang asked me to pass on the message that the reason for the display issues was that some supervisors accidentally un-verified their entered scores. Everything has now been restored.

Is there any other score higher than this? That moment when you have perfect mass score but your hovercraft is still too fast and gets destroyed on time. Such is life.

Troy destroyed everyone in terms of the test, according to the supervisor.

Our B team got a mass score of 1860, time of 12.4 ==> 47.4435 on build. Our A team got a full mass score and a time score of 9 ==> 34 on build

Our A team got a 35 on test, our B team got a 26.

B team ended up 7th, A was 8th.

therefore 47.4435 + 50* 26/x is slightly larger than 34 + 50* 35/x (let's say the difference is 2 points, which is probably being somewhat generous)

Thus the max score is between 35 and 39

Could you explain how you got the 35-39 range for the test? Quickly looking on Wolfram Alpha, it seems like the max test score just has to be more than 33ish

Well, I already got 35 on the test... The 39 is because we're guessing that the scores were reasonably close.

If you simply solve the equation 47.4435 + 50* 26/x = 34 + 50* 35/x, you would get x = 33.47.., but by assuming the difference between the two teams is 2 points, you solve 47.4435 + 50* 26/x - 2 = 34 + 50* 35/x, which gives you x = 39.32... However, with one of these teams getting 35 points on the test, the minimum of the max score must be 35. At least that's what I think the thought process is.

Plus, since Troy destroyed everyone in terms of the test, I would guess the max score to be in the 40s at least (which you will get solutions to if you assume that the point difference between the two AB teams is greater than 2). For instance, if you assume a point difference of 3, the minimum for the max test score already becomes 44 (round up) and increases more as this point difference increases.

Thanks for the explanation :) I was under the impression that the 39 was some sort of hard limit.

Oh, no, I assumed the difference was 2 points because I figured that it'd be somewhat close, the more leeway you allow the larger the potential max score is (although I would put the difference at no more than 5)

What types of difficult questions were there on the test? So far, at regionals and the invitationals that we've went to, the tests have all been obscenely easy... I hope that the states' test will be a little more challenging to spread out scores.

Iirc I talked to the supervisor right before he went in for score counseling and he said Troy won by a 17-point margin (/100), or somewhere along the lines of that. So I'd imagine the scores were not actually that close.
