Average difficulty rating - show wrong or multiple sessions
A yellow/light blue highlight in the time distribution charts highlights your time, where relevant.
Rating scores out of 10.0 show the average difficulty rating chosen by users, where 1.0 is "Easy" and 10.0 is "Hard".
If a puzzle is opened more than once, including by loading from a saved position, then this is potentially a significant aid so it is listed as being completed with 'multiple sessions' for the purpose of the best time/average rating displays above.
Minor aid is defined as no more than one use of 'Check solution' when incomplete and/or no more than one use of 'Check solution' when wrong; and/or using highlighting aids (show repeated digits, show broken inequalities and show valid/invalid placements [slitherlink] only). Major aid is any and all other use of the solving aids except for 'show wrong'.
Interesting is the comment by martint: Link
I wonder how martint knows his negative time while his status says "has not yet finished the puzzle" (as of now).
There, it seems, a result with a negative time is not stored as finished in the database at all.
The time will show negatively when you finish the puzzle in the player window, but it then won’t trigger the “solved puzzle” status because it doesn’t fulfil one of the requirements, of having taken at least 15 seconds or some such time that I forget but set once upon a time many years ago.
How is his completion time 1:08:28 ?
If clocks haven't changed in kosegi's time zone, then the difference between that time and UK time will have changed by +1 hour.
And in fall/autumn it doesn't matter where you are, the difference between the UK and your time zone changes by -1 hour, unless your own location changes the time at the same moment.
When it comes to databases, the only thing worse than timezones are timezones with DST...
