It's kind of insulting to the reader that they explain P complexity class without using the word polynomial ("all problems that can be solved in a reasonable amount of time")

Be generous - it saves a lot of time. Once you say "polynomial" readers will think, "like, ANY polynomial, even like n^100?!" and you'll have to explain, yes, but that's STILL better than exponential, etc. They avoided all of that
