I have no objection with him posting results It's too unwieldy for new users, though, to be the "official" run. Part of the idea of the league is that you automate it to see how a version of your bot does compared to another version. You need a ladder for that to make sense.
But since F1 is presently on hiatus, bac's method fills something of a vacuum, so I guess I shouldn't complain
To set the record straight, I don't believe bac or anyone else wants to run this league the same way in the future.
You can agree that is the top of the league there where some weaker bots, that where defended by Excalibur. This league table puts a more serious kind of leaguetable then one where guardian was even in the league.
I would (as far that wasn't clear already) like to propose this as the new league table, and let all new league-challangers be run at the old way.
Perhaps develop ranking like in chess, where eveybody has a point average. I don't know the details, but if a low point beats high point he gains a lot (and the high looses a lot) if the low point looses he looses a little (he was expected to do so). In such a system you don't have to play everyone, you just organise appropriate contests. It allows for incremental updating if a new player appears.
No, that is complicated enough. If you look into it a rating system as with chess or draughts could be complicated to setup in DB, I wouldn't know where to start, to me this sounds as an 'líttle' absurb proposal.
To give an example for the complexity, there where multiple chess/draughts worldtitelskeepers that kept first in the ranglist by not playing (almost)any game for serveral years. One of the best proposals would be the only ever chess-world title holder that came from the USA. He got the worldtitle never payed again, and it took years after that he won it to lose it. Another one would be the current tittle holder of draughts. The dutchman Ton Sybrands didn't really played that many draughts matches the last several years. If believe he has quit now, but it will take time before official ranglists get it.
Just some random useless knowledge I know from thinking sports.
