1st place 4.18 g - loaded to 13.625 kg --> old score was 3260 and new score would be 44.4
2nd place 5.42 g - loaded to 15 kg --> old score was 2767 and new score would be 41.5
3rd place 4.53 g - loaded to 12.22 kg --> old score was 2698 and new score would be 33.0
4th place 5.44 g - loaded to 13.745 kg --> old score was 2527 and new score would be 34.7
5th place 6.19 g - loaded to 15 kg --> old score was 2423 and new score would be 36.3
6th place 6.05 g - loaded to 14.58 kg --> old score was 2410 and new score would be 35.1
7th place 6.56 g - loaded to 15 kg --> old score was 2287 and new score would be 34.3
8th place 6.29 g - loaded to 13.935 kg --> old score was 2215 and new score would be 30.9
9th place 5.14 g - loaded to 10.895 kg --> old score was 2120 and new score would be 23.1
10th place 6.47 g - loaded to 13.495 kg --> old score was 2086 and new score would be 28.1
I also computed new scores for places 11-30. The interesting thing is that after looking at 1-30 with the new system, the top 10 stayed the same, and only their order was changed. The third place tower from 2006 ended up in 7th with the new system and is the one that changed the most places in the top 10. In places 11-30 from 2006, the 19th and 21st place finishers would have ended much further down under the new scoring system, probably 2/3 to 3/4 of the way down the list. They were light towers that failed at low loads (4.92 grams and 6.815 kg for one and 3.83g and 5.065 kg for the other).
So, there you have it from 5 seasons ago. A grand total of 2 C division towers would have scores above 40 with the new formula. So, based on this, I'm changing my previous position and am agreeing with rjm in that anything above 50 will be breakout new technology. So, scores above 40 will likely earn medals in Wisconsin next May for both B and C.

I ask because no matter how simple i make my design, i don't think it could get below 7 grams.

But, if you want to do really well, this is just a necessary part of the process. You can design the best structure, but unless you select the right materials its just junk.

If a lever system is used to let the sand fall in, would you want to go slow, then faster, then switch back to slow? Letting the sand in slow seems like it would make your tower sustain the weight for longer times, but faster streams seems a bit all of a sudden.
And if there is a manual sand system, then I would assume you would try to pour the sand around the bucket evenly, so there are no mounds, and try to do it as quick as possible?
