The first original calc is here.
It was accepted, but for some reason, the calc was never added, anyway while I looked at it I realised that some parts of it were wrong, and that Tsuna's output was greater than waht the original calc said.
I know some people cannot see the pixels, but the website I used gives you the amoun of pixels already, so if you can't seen just look at the first box with the number in it.
Ships of the Maersk Triple E class have a length of 400m.
400m = 14px.
400 / 14 = 28.5714286m
28.5714286 x 90 = 2571.42857m
2571.42857 / 2 = 1285.71429
1285.71429 / 476 = 2.70108044
2.70108044 x e-0.33 = 7.01229788
7.01229788 / 0.28 = 25.043921
25.043921 x 5000 = 125219.605

This should mean Oath Flame, Curse of the Rainbow Arc and Ultimate Dying Will Tsuna are definitely 6-C.
