I don't have anything to contribute (just reading an interesting discussion), but isn't this:

Without ABS, no matter how accurately the f/r bias is set, and no matter how skilled the driver, during trail-braking you are limited by the grip at the unloaded inside front tire, whereas *good* ABS it will prevent the inside front from locking, allowing it to continue to contribute to lateral grip, while at the same time allowing the outside front to brake harder and closer to its higher grip limit.

In conflict with this?

Sounds like "good ABS" (which I take to mean good management of front/rear and left/right brake forces as well as not going full ABS when there's still grip available to some of the tires) would be worth more than a few tenths.

Yep, hence a grip
circle.
