Hmm. Maybe something like the appended? Together with making the time
modification be 10 seconds to make Simon happy (that's what Jiri
originally did, it was me who said "why not make it a natural human

4?) and avoid the nasty division..
Patch is whitespace-damaged and totally untested! Caveat applicator.
