True, considering for how long this has been this way....
After all, a Pristine Metallic Asteroid Belt Cluster sure is more useful/valuable than Icy Moon #9 around a Class 1 Gas Giant?
And they're not all the same size, some are very large - thus their value can be variable just as well.
IMHO they could even show the 1st Discovered, it's being correctly tracked per Cluster ever since. And displaying multiple CMDR Names (at least the Top 4) would be possible, see Wing Exploration and their display of 1st Discoveries.
