Massive chart is basically a collection of what people do in their own darkroom. We know nothing about individual's shooting styles, metering skills, darkroom skills, accuracy, and everything else that will affect the result. In other words, it is useful to see what people do but they weren't done to a single uniform standard. Kodak's chart is made up of what Kodak did in their lab under very controlled and regimented environment. Personally, I use only Kodak's tech publication as my starting point.
As Matt says, Kodak publication does have time for Tmax 100 in 1:1.
