Work in progress my friend.
That little thread of mine is still a work in progress, and needs an update. Again.
The only thing that Sarah Forst says about an upgraded master cylinder is this:

Unfortunately she does not address bias nor proportioning valves. Although everyone should still go buy her book.
As you know, you can degrade your overall braking performance, if you upgrade the fronts, rears, or both without taking into consideration the proportioning/bias. Bigger brakes that are not "locking up" at the correct time, nor utilizing all the friction of the four (4) tire contact patches on the road, are going to offer worse overall stopping performance than a properly engineered brake system with smaller actual brake components.
