The EM Potential system, while around for decades, exists for the vanity of the higher levels.
'He knows how to pick 'em - whoee, that un was a sure good pick.'
It has been used in Military establishments since Rome - since Ur.
Also in the various Religious establishments over time.
In the Governing realm, its been hobbled by inheritance and wealth rules, but in a democracy this 'Potential' system is also used.
For example, in our current US environment, there are several candidates vying for the best 'Mr. Smith Goes to Washington' imitation and mantle.
But the people will pick that out.
In EM - along with most corporations - the Pecking Out continues to be one of the non-monetary methods to keep the interest of the Executives. Keep them sharp, competitive, best-in-show.
It is sporty - takes a good coach to build a good team. Free-throws count.
It is smart - knowing there's only a few out there with the right neurons and drives.
It is lusty - Ginger or MaryAnn. Maybe a Samantha Stevens twitching the nose. Rock Hudson.
It is worry-free. I'm on top and 5-6 years from platinum handcuff freedom.
OP - I'm just describing the system, but to answer your question.
You are stuck in your original classification for top CL.
It's like a forehead tattoo.
