Until someone tests it and shows some data you're just guessing.
Many are claiming it is an "educated" guess. Just because there is some data available doesn't mean it is informed. You need the right data and enough of it. The UDUStats site basically is the same thing. People say it is a good reference to estimate if an upgrade will clear or not but there have been routes with data suggesting that 1Ps cleared more than 1Ks. It is woefully incomplete and nothing we do is going to make it sufficiently comprehensive to be useful.
