He didn't improve by a lot, he just said what I said in more detail, made it look prettier, and added a source which is good but unnecasery since it's almost common knowledge that scald has a 30% burn rate and nothing otherwise has been proven against it. If this were some sort of controversial complex question about theory and junk, I would have definitely put in a source. Otherwise he didn't do anything that helps answer the question more than I did.
