Aganju: ~~I think you misunderstood me. Of course, seeding every time as well as seeding only with the minutes is not a good idea; this was my try to reverse-engineer the experienced behavior here on BK.
That doesn't make sense. if you know it's a bad idea, why would you suggest it as the likely reason?
~~As I wrote below, if I play a move in five games within one minute, all my opponents have the same roll afterwards. That seems to point to a) the roll for the opponent is made the moment I send my move, and
This is certainly the case in games with auto-pass as it's necessary to know whether or not the opponent is blocked.
~~b) the minute is used for seeding every time, so that would explain why they all have the same roll. That's only a guess, of course, but one that explains what's happening.
I would assume a bug before considering bad programming of something so straightforward.
~~Because all my opponents answer at different times, typically this is not very obvious, but if you note it down, you can check the games and verify that they all roll equal.
I think a much better reason than positing poor programming is to suspect the data acquisition. If you've done a Masters degree then you know that it's all about evidence - extensive and methodically recorded evidence. If I were to take the claim seriously then I'd want to see what you've got.
