Re: Competitive Times for Nationals
Thats a combination of time and accuracy. The time score is the time in seconds multiplied by 2. The accuracy score is the distance from the target point in cm multiplied by 4. The total score is the sum of both values, and a bonus of -25 points if you make centerline bonus.
We are discussing time score, so I was essentially asking if anyone has seen cars that cover the distance in 2 seconds or less.

Yes that would make sense, my team's score was around -12 or so.RyanMist wrote:I don't compete in this event and I am not completely sure about the rules. I think our team got a negative number of points and we got 2nd at states. Again I am not sure if this is true but I'm pretty surejcmarcus0816 wrote:shrewdPanther46 wrote:Has anyone seen time scores under 4 points at competition? What were the best times of cars you have seen where the accuracy is still competitive?
I'm getting worried that the speed of my car will not suffice after my partner and I slowed it down for accuracy, so I would like to know the kind of times we will all be seeing at nationals.
My partner and I got a time score of a little over 5 at the Michigan state competition with a distance score of 8, and we got first. At one point we did have a time score of under four but the car skid so much that the consistency was completely wack. There are some ways you can get the car to take a longer time to slow down to reduce skidding but we did not have enough time, so we just slowed our car down to about 2.6 seconds. If I were you, I would just focus on accuracy and make sure your car can run under 3 seconds.

Would be sheer luck to have a 2 second car be sub 2 cm accuracy. Not to peel out the car would need to be heavy, and then there would be big skid issues.shrewdPanther46 wrote:Thats a combination of time and accuracy.

Well if you could pull of what Troy supposedly did in EV, it could be possible.

Re: Competitive Times for Nationals
Troy's accuracy was a bit shotty, but their times were between 1.1-1.3 seconds and it was incredible watching them test they day before competitionhippo9 wrote:Well if you could pull of what Troy supposedly did in EV, it could be possible.

Re: Competitive Times for Nationals
That's not true at all whatsoever. If you have a heavy car with a consistent braking system, it is definitely possible to avoid skid issues as well.builder83 wrote:Would be sheer luck to have a 2 second car be sub 2 cm accuracy.

NOTE: This is just my theory, as I am sure that if I really wanted to, I could push my times down.

Re: Competitive Times for Nationals
my partner and i were discussing this a little today.
If our car goes around 4 seconds, its an 8 score.
if it goes 3 seconds, its a score of 6.
if my car is 3 cm away from the point with 3 seconds, the d + t score is 18
if it is 2.5 cm away from the point with 4 seconds, the d + t score is also 18.
It is very easy to get that 0.5 cm closer, and much more consistent, rather than boosting the voltage by a battery and having skid.

Score is determined by time (in seconds) x 10 + distance to target (centimeters)
1st place Mounds View: ~16 points - A score of 20 would mean that their run was 2 seconds and 0 cm from target. iirc, they had 0cm off and 1.6 second run.
2nd place Boca Raton: 20.7 with a time of 1.79s and distance of 2.8cm
3rd place Troy: ~21-22 with a time of ~1.3 and ~8cm distance
Granted in EV, we had integrated circuits and brushless motors.
Addionally, weight does NOT result in skid issues. It may increase momentum, but it also increases normal force and I found that I could control skid quite well despite the heavy device (2-3 kg's). There are plenty of little things such as cleaning the floor, "conditioning" you tires, and adjusting weight distribution that can have large effects on reducing skid.
