Because the chart was to compare what new core oils, matched the old Schumacher oil. If there was no direct comparison with 450, then I guess it wouldn't be on there.
For there to be a chart to compare to other brands, someone would have had to bought them all - which is kind of unlikely i'd think. We have compared 450 core to 450 Much more and can't tell a difference. In theory, cst as a measurement actually means something - so there should be less variance between brands. "wt" never meant anything! I think one of the RC companies invented it (probably AE).
