Boy, that sounded all smarter than I intended.
No, nothing to do with the government math.
I simply mean that the traction circle you are referring to is not a circle. You may have reached the 100% limit in sideways traction but you still may have traction available for braking. Years ago the traction circle was like you described - a zero sum game. Any traction used for turning was not available for braking. The truth is not that simple anymore.
The real world traction "circle" looks like this.
