From memory, Level Deep and Level Quick are obscure software (app?) development terms. I could be wrong. Then again, given that this Skeptic's site accepts proof in the form of, "I heard it a few years ago," I am at least on as solid ground as Vixen. Maybe Quennell will ask one of his 100s of lawyers to sort this out for us.
Level quick is a substance when mixed with water can be poured on a subfloor. When it dries, it dries level and apparently "quick"-ly.
