Dunno about that - but when TL was introduced there was a chance to make the averages over the last 200/500 rounds and keep it rolling that way - but no, the same system was kept rendering these averages as meaningless. When I reached saturation my average was 61 - now just dipped into the 58s - so no longer a rough reflection of my ability at all.
Might as well just list the names and their level.
