You're right ... nobody will ever get any information, but you're also right that
it's very easy to address, which is why I don't understand why it hasn't been
done yet (could it be some legal reason like someone would complain that his
time has been removed??)

Anyway, to illustrate how easy to is, those few and simple conditions alone get
rid of all the glitched times I've encountered:

if (time)<1 sec or (#zones)<1 or (#pads)<1 or (#perfect zones)<1: invalid
if (time)>540 sec (9 mins) or (time)<16.5*number_of_laps: invalid
if (#zones)>=75 and (#zones>#perfect*8 or #zones>#perfect+100): invalid
