Rating Bug

I suspect this discrepancy could be due to fact that ranking ordering is recalculated not instantly but about "each 15 minutes". Could this be the case? Currently it looks already updated...

BTW it was funny to see how you with Guy made several attempts one after another, each time jumping forth :)

Yeah, the Color Cubes challenge is seeing a lot of action today.

(Is it me, or did Kronoc lower his previous score?)

Yes I think previous score of Kronoc was greater!

Meanwhile I'm not quite happy with scoring of challenges. Result depends both on specific formula for each of them (i.e. on challenge internal score) and some arbitrary chosen factor.

I could not remember why such a clumsy approach was implemented, but probably it is worth changing it to some less vague one?

For example results of the challenge could be still ordered according to the formula, but enlightenment bonus should depend only on the place of the user in the given challenge... Will such a change be accepted by participants if we try to introduce one?

I see no problem with changing it. The current method often gives very low coefficients; I'm sure something better can be devised.

The system used here is interesting and might serve as inspiration. Those challenges are limited in time, so adjustments might have to be made as to not discourage future participants.
