@ rosewood2: You are probably right... but I think an upgrade should only occur when the penalty was not served:
/setpenzone=5
warning, warning, warning, warning, warning, dt (served), warning, ...
warning, warning, warning, warning, warning, dt (not served), sg, ...
@ Gutholz: I, for my taste, rather have things like this or like an in-game tracker, I once had the idea for here as well, hard coded in the game, sothat one does not have to rely on third party products, especially when these things are helpful for racing.
