Oh my god i just realized that i most certainly got a lower/better score than you (no offense sorry) but i got 20th and you got 14th and i'm trying to remember if we ever turned in the graphs. At first we tried to turn them in right before our run but they told us that they'd take it later. i dont remember ever actually turning them in. ahhhhhh!!! I need to check or impound box for the graphs tomorrow. hahahahahaha if we forgot to turn them in then that is the second most stupid thing I have ever done at nationals!!! :lol: :lol: :lol: :lol: :lol: :lol: Wow they'd never let me live this one up.

Our device was pretty good for any targets shorter than 7 m (and 6 m high), but they of course decided to give us a target at 6 m raised to 1 m and an 8m target. Thus, we missed the first... and the second (we landed about 10 cm outside the target area). Not shockingly, we got 56th :lol:

Our device was beautifully accurate for any ground target (within 5cm accuracy), but because our settings for targets between ground and 2m were based on non-linear calculations with relatively few data points, we got about 30cm off at the 1.4m target we were given at Nationals (exact same target as at NY States, btw, which we didn't expect, even though we knew it was the same supervisor). We messed up our second shot on the high target, so our 30cm on that target was our best, and we had about 5-10cm on the ground target on our first shot, so we took a bucket shot.
Unfortunately, our laser (which was a "Danger" laser- actually less dangerous than the "Caution" ones, I think, but I forget what order the different warning labels go) wasn't bright enough to show up under the spotlights that they had shining on the Trajectory area, and so our bucket shot was the perfect distance but about 15-20 degrees to the right :( . We got 15th, though, so it's all good (that's the best my school has ever done in Trajectory...).

My coach told me after the coaches meeting that we weren't allowed to bring in lazers that said "Danger." He said only "Caution" was allowed, so we ripped the lazer off before impound. It didn't really matter because the bucket shot was 8 M out and 2 M to the right. We'd only callibrated to 8M, so even if we had the lazer, we didn't have the callibrations for something further than 8M in a straight line (I'm guessing the bucket would be something around 8200-8300 in a straight line).

My first shot at the close (6M, 1M high) was 200-something mm and the second 140-something.
My third (8M) was 60-something mm and the fourth 20-something.

16th place. Not perfect, but I'm pretty happy with it since I've had some really bad encounters with devices at state.

Did anyone else see the absolutely cute plastic cup and duct tape pulled back by a string in C division? It was so funny, but I felt bad for that team because FedEx lost their device...
Really? I was thinking more along the lines of -400 for first (about 7 cm off each target, two bucket shots- one hit the bucket and bounced, the other went in, full graphs, and no penalties) and -200 to medal. Seems reasonable, but I have no idea.
Well, I'm not sure -400s are possible. Are you talking about C division? Because I was talking about B division...
Nope, I'm talking about B. A perfect score would actually be -600 (0 points for hitting both targets dead center, -200 for both bucket shots staying in, and -400 graph points, with no penalties). At least that's how I interpreted the rules.
Our device was pretty good for any targets shorter than 7 m (and 6 m high), but they of course decided to give us a target at 6 m raised to 1 m and an 8m target. Thus, we missed the first... and the second (we landed about 10 cm outside the target area). Not shockingly, we got 56th :lol:
So basically they gave you the furthest possible targets?

You start with 400 points, which the graphs should eliminate. So the perfect score is actually -200.

:oops: Oops, my bad. Just add 400 to any previous estimates I made. Great, this means the score I posted on the score tracker should actually read 227 instead of -173.

The graph points work out that you start with 400 points, and if you get full credit for your graphs, you lose those 400 points. It's not -400 from zero, it's -400 from 400. So a perfect score is -200 (start with 400 points, lose all 400 for graphs, 0 for hitting the pin on your first shot on both targets, -200 for landing in the bucket twice).

We must be the luckiest team in the world, because we had no data from 5 meters to 10 meters but we got a bulls eye and 20 or so centimeters off the second target... placing in the top ten...

Good gosh, luck was on your side. Someday, sometime, my team will get a bullseye in trajectory...
