I really don't think any of the TPGs will ever be able to put together a registry flexible enough to truly cover the subject..And I'd think pins or whatever would have to be acceptable fill ins..

Maybe just a career contemporary list. with a +(#) for years removed from the decidedly acceptable rookie card year..

Take Feller for instance. Let's say 1937 is decided(with the goudey wide pen), and someone has the 1941 double play as his card. It would then count as having a card/item of him with a +4. Compile all the +numbers at the end on top of completion %. That way even without improving your completion%, you could still improve your set/collection.. Say you're at 87% completion, with a +85, simply improving the age on that 1 card, you'd move up to 87% completion, with a +81..

maybe even create a highest possible +(#) for a player. Again, I'll use Feller as an example..If it's decided that his acceptable rookie card year is '37, and the last year he played was '56, then his max +(#) would be 19. If you don't have a card of him, then you get a default +19 until you get a qualifying card.. Compile a highest possible default number(combining ALL players) at the start..And then just subtract from there when applicable cards/items are added.

Just estimating. 300 members, at an average of 15 default years apiece. Maybe everyone starts with a max number of 4500(whatever the actual number end up being) and working towards zero.. The near impossibility of some players would basically create their own weights. You could technically have ZERO Rookies, but possibly still have the highest rated set with a number of +300

And for players with no contemporary items, you could cap it at first reasonably attainable non-contemporary card/pin/whatever).. Or just discount them alltogether..

Just some random ideas..
