[Parley-devel] Graduated interval recall

[Juergen :-)]

Hi,

regarding the timing when a vocabulary should pop back for test I was 
impressed when using an audio language course "Pimsleur language" course 
(they say it's the only one that works :-) ). Although it doesn't differ 
much it has this very interesting system of "Graduated interval recall" 
- see link.

I have tried this myself and it works very well with me. Maybe we could 
replace "random" recalling with these intervals?
