I don't really know for division B, but I seriously doubt that that will be the case for Division C
I think in 2014, the div C winner hit around 2300
I think the rules we are using this year are those similar to 2014 and the winners for Division C with the 20cm height was around 1900 and 6th place around 1300. I might be wrong but I know it was near that so I’d expect it to be lower

I was thinking of the top 6 placement score, but you are probably right actually; not only were the scores closer to 1800 than I thought, but teams generally also get better each year.

For Div B or C?

I saw from pictures of previous national boomilevers that they all had the loading block tilted. What is the purpose of doing that?

Titled what direction?

I meant placed diagonally on the compression member.

My assumption is that they made a gusset joint there for strength purposes between the main compression and tension members. I have no other idea as why they did this or if this style is more efficient than the conventional designs.

Do mean that they're like, rotated 45 degrees to one direction? If that's what you mean, it's because some tension boomilevers don't have space to fit the 5 cm by 5 cm loading block "regularly". Thus, they rotate the loading block so it can still rest on the boomilever.

Does that make sense?

If the loading block doesn't touch the corner, the resting place will be slightly weaker. I suspect the 45 degree tilt is so that the tension members can extend closer to the actual position of the load (center of the block) without running into the sides of the block, and still keeping the boomilever width small.
