names color coding

[vlsup]

In Default stat config we can see the stat named "Abb.name" is color coded. The other are too, but I understand their colors depending of values.
What value of what parameter makes this stat "Abb.name" to change color?

If so, it is not a problem to have a stat "M" (by Harrington)?
It is very important for tournaments with multitabling - to make qiuck decisions in push/fold, for example.
Can I create it manually, or have to wait?

Divide BBs by one and a half, ignore antes, and paint result according to book - here it is!
