@AmpharosBoy@NykromantykSo, as I said before, let's say Peter Parker would have a 20 in every category (except Mutation). A 50 in Strength would imply you're 2.5 times stronger than Peter Parker. So, depending on the author, you could lift anywhere from 25-60 tons. But that's only if you're going super precise. This is mostly to gauge who is capable of what in relation to your fellow Spiders.
Oh, and by the way, everyone, my CS is inbound.
