Average Calculation in "My Profile"
How are averages calculated? Are they weighted by time at all?
I switched computers and have suddenly discovered my reaction time is 100ms better. Apparently my linux net book was somehow slowing down the results. My average is going to be artificially improving for a while.
On a slightly related not I thought one neat feature would be the ability to zero the base scores to ones current average so you could easily compare your scores against a snapshot of them at a different time.

The small differences between systems definitely pose a problem. You may want to look into this for any latency issues on your system: http://www.thesycon.de/deu/latency_check.shtml
Averages are calculated in a simple manner: after a number of baseline scores have been obtained, they are averaged (added together and divided by the number of data points accumulated). The process continues with each additional test you do for which a score is recorded. This makes it impossible to find a "current average" based on some arbitrary timeline, because the timeline begins when you first started. Instead you could get a new account and then compare it to your old one.
As far as I know, no weights are applied, but z-scores are given (as you know) for various tests. Essentially, your improvement is calculated in terms of cogfun's population's performance. (If all scores are green, then you're "above average".)

Once all your scores are in the green it isn't quite as interesting to look at anymore. And it's harder to notice changes in performance.
Making a new account is a good idea, but I probably won't do that. More ways to look at your scores over time would be a nice feature for this site in the future.

Yep. Can't agree more. I hardly use the site any more. I like answering questions and pestering regulars, though!!! :-D
CogFun has not made any updates for a long, long, long time. Interest seems to have died out; but it's good the website is still up.

I disagree. All my scores are green, but I still seek to raise them, looking both to the absolute scores, my own prior scores, and the % by which I exceed the "norm." I take it the norms are simply those using the site, so they are likely very far above a population average. I also do look at the charts of recent scores and seek to match whomever is "beating" me.
