Ok I tried my best to explain it to you in the other thread but I seem to have failed.
I created an addon for you: oUF_Doom.

It does exactly what I described in the other thread. Create a fake statusbar for value updates.
Create a texture and apply the value changes via SetTexCoord to that texture.
