As i watched the torrent i noticed that the files are downloaded completely at random. That is to say if you have 10 files, each 200mb, by the time the torrent is downloaded 10 % you can have 1 full file, or 80 % of one, 20 % of another , 10 % of all and so on. If you played a game, which is you bet on % of the total downloading of a torrent, and you win if the difference in mb between the most downloaded file and the least is greater than other person's > what percentage should you bet. Then you play the same game, but this time the goal is the sum of the first 3 files to be exactly 85 % greater than the sum of the last two. Also you examine the possibility of being an interval of numbers, when the chance is greatest, or the problem may not be leginamite at all and in this case, please tell why.
