Because after spending more than 5,000 hours playing nonosweeper (EWQM and Stephan certainly invested a lot more) I just know that their scores are possible.

@Lutz: Was curious how much time I really invested...

- I currently have 16,369 screenshots of T boards which I finished and which I saved a screenshot of.

- I rounded up all times to the next full second, e.g. both a 1.01 or 1.99 will count as 2 seconds played. (This is a unprecise assumption but saving the screenshot definitely always took longer than the missing part of the full second

).

- The sum of these screenshots is 449,956 seconds.

- So, this is roughly 7,500 minutes or 125 hours.

- Unfortunately, this calculation doesn't take into account the time invested for unfinished games

, but even with a finishing quota of 10% only, the total time would only be 1,250 hours.

- 5,000 hours by my ~600 participations would end up at more than 8 hours per grid. This is probably too much, at least in the last few years.

=> I think I invested less than 5,000 hours for Nono T boards. Maybe my wife wouldn't agree

.
