@f0x It wouldn’t make much difference. Torrent clients usually pick random blocks to download and don’t download sequentially because doing so would hurt the health of the torrent.
If 10 clients download the first 20 MiB of a 100 MiB file, they are still be dependent on the seeder for the rest of the file. If they pick random blocks, they can download from each other, even if the seeder disappears.
