Rating on new submission

I came up with the similar proposition recently:
viewtopic.php?f=27&t=2198&p=13923#p13897
so +1 from me. it would be really REALLY helpful.

The problem with this is if we are wrong and the new bot is of a much different rank. Any bot in any game the new bot would have an incorrect rating adjustment.

[Equinoxe]

If the new bot is of a much different rank, then the sigma increasing (for example to 16.67, as at the beginning) would, I think, be sufficient to allow the bot's results not to influence too much the other bot's rankings, and to get faster to its true rank.
On the other hand, if the new bot is for example xathis v3, and the system that is used nowadays is used, will perturb every bot it will fight against from the lowest ranks to the highest ones.
So the only change of increasing sigma instead of setting values like at the beginning is that bots will take less time to converge towards their true ranks, and so will less disrupt other rankings.

So, maybe could there be a choice on resubmit.

People would have the choice between resetting their skill - and therefore checking they are still doing well against lower ranked bots -, and keeping the same skill - and so seeing whether they improved their bot more quickly.

What do you think about this ?

The issue becomes then that it is harder to code. On the other hand, choosing whether or not you want to reset mu it done in 1 HTML code line, 4 PHP code lines and 2 SQL code lines. (Add the checkbox, if checkbox then newMu = 0 else newMu = <Request old mu>, and change the request in order to set mu as wanted)

I think resetting the rating worked out fairly well. Most of the downside was mainly a result of the low game rate and would be minimized so long as the game rate could be kept at or above a game per hour. With that a new submission would be facing challenging opponents within at most 7 hours and be pretty well ranked within a day.

The easiest way to get the game rate up is probably to choose a game that has a maximum length of about 250 moves and an average around 150 or less.
