Solon, if I remember, got 97 and change.

Mr Steven or any other illinois builders, do you know what the efficiency of stevenson's tower was because they won...

Stevenson didnt win
Assuming they used the same design and wood for their regional/state towers, they were at 70 cm full load & 9 grams +/- .5g
Work the score from that no calc in front of me...

Although idk if they changed anything from states to nats but i wouldnt think so..

yes they did, this is from illinoisolympiad.org, state results:

Towers
Place Division A Division AA
1st St. Charles East Stevenson
2nd Farmington New Trier-Northfield
3rd Canton Libertyville
4th Collinsville New Trier-Winnetka
5th Lewistown Champaign Central

EDIT: it seems we both misunderstood each other, I meant what was stevenson's efficiency because they won STATE.

Not too shabby

yea, about 6.9-7 grams assuming it was 70 cm and held all mass

I had a full height 6.67 gram tower hold it all about two weeks before our regional tournament this year, and unfortunately I wasn't able to replicate it all season. But, that's how towers goes. As frustrating as it can be, I'll miss it next year.

Yea, sometimes you just get some lucky balsa/bass.

A week before Nationals, we made a 7.2 gram tower that held 13 kilograms. We thought that, by increasing the weight (and strength) of the tower, it would hold the whole thing. So we brought an 8.6 gram tower to Nationals, confident that it would hold full. It broke at 11.5, because one piece popped off, making the chimney shear and twist. At least we still got 16th.
