It's stupid, isn't it to keep tinkering with a "system" that's so arbitrary, and not a system ?
They are having to cram more "space" into the smaller end of the spectrum...ultimately, they will have to go negative.
A simple rating, of some cold temperature performance parameter (in real numbers), HTHS (real numbers), and (something like) an API performance rating would help the consumer, once educated to make a rational choice...the highest 20 and the very lowest 30 are really the same, and a new rating system would show that.
