I looked at the reference calc for destroying a skyscraper and noticed quite a few weird things about it.
Why does it use shear strength everywhere? I thought that was just used for cutting feats. Destruction feats like this would use the destruction values from our Calculations page, which would put Reinforced Concrete's destruction 2.8x lower than this calc has.EDIT: I have been informed that shear strength is our basis for frag, we just revised the values, leaving this 2.8x higher due to being outdated.- Why does it use the separate materials used in the construction of concrete and then add up their destruction values? The whole point of making concrete is that doing so changes the material you get. The stuff that's used to make concrete does not have the same properties as concrete. This gave results ranging from 2.3x higher to 2.6x higher than the already inflated
shear strengthoutdated destruction values do (I have no idea where that 0.3x variation comes from). - The first method takes the mass of a skyscraper, and instead of directly using the density of concrete to get the volume, it gets the density of the components of concrete (which have 1.54x the volume of the final product of concrete), uses them to get the volume, and then never adjusts the volume back down. Despite the weirdness, this only gets a volume 1.04x higher, not super wrong in final result, but just very strange.
- Earlier on in the calc it was just using Cement, Silica, and Granite, but in the last calc for melting, it included Silica, Alumina, and Granite, admittedly ignoring Cement. From a quick search, I found this page giving the specific heat and melting point of concrete; when I plug those into the volume the calc used, I get a result 1.5x higher, without including latent heat of fusion due to me being unable to find that.
- Why does this calc only give a melting value for the far higher estimate of skyscraper size?
- Why does this calc use two different estimates of skyscraper size, one of which is 29x higher than the other, without saying which one is the reference for this common feat? It has values almost 67x apart (with the highest frag one being 187x off what I think is most reasonable) despite meaning to be a common reference for a generic feat!!
