wink wink( that isn't true but it would be pretty funny).

Also, Ivan got like more than 30 sec off the target time lol.

The time was 37 seconds and we got 7 Lol.

That's great actually. That's exactly what I'm saying. If you do the optimization, the best way to get points is through jumps. You need height to get jumps. You use all the height you possibly can to get the most total jump distance, then use whatever is left over to get time. Time Score and Height Score are irrelevant. You only need to focus on the Gap Score. The optimization is not very well balanced this year, but it is what it is and congratulations to Gelinas for figuring that out early and getting such a high score from gaps alone.

Yeah, although I doubt that was their intent, that's what ended up happening. In my design I had the first 70 cm o height devoted to gaps, and then left 7 cm for time adjustment, which I was able to get within 3 seconds of anything below 40 seconds.

'7 cm for time adjustment, which I was able to get within 3 seconds of anything below 40 seconds."
wow, this is bitconnect level skill. pls tell how u got so much time out of so little space, I seem to be running into the same problem as others who have devoted vast quantities of "free real estate" to gaps.

If you use a magnetic ball with a non-ferromagnetic roller coaster such as aluminum, you can slow the ball down a lot.

But be warned, event officials might think the magnetic ball is not allowed because the rules say the roller coaster cannot have magnets. However, in my opinion, the ball is not part of the roller coaster (the rules make a distinction between "roller coaster" and "vehicle"). Also, a magnetic ball will not be attracted to a non-ferromagnetic material like aluminum when not moving. It's only when it moves that the ball feels a retarding magnetic force because of dynamically induced electric currents in the aluminum as the ball rolls down.

In my opinion, this is using science to come up with a better engineering solution, which is what Science Olympiad should encourage. Unfortunately, you will likely get tiered with a construction violation if you do this. I have submitted a FAQ question months ago on this, but no response.

What is the largest total gap bonus teams have in cm?

eyyy this induced eddy current is appearing all over the place. nice idea m8
hopefully the ES doesnt get triggered

hmmm, i want to see a teams roller coaster use magnetic levitation, that would be lit

bruh thats just against the rules lol

Technically, the rules make a clear distinction between the roller coaster itself (which cannot have magnets) and the vehicle (of which little is said except in a FAQ that says it must be spherical). Like I said, I asked a question about this specifically months ago, but no response. Not going to risk it at State unless an FAQ comes back and says OK.
