Many actions are traditionally performed in order of ship Id. Since this gives players with low-Id ships advantages over those with high-Id ships, PHost starting with version 3.4e/4.0a will perform certain operations in Per-Player Id order:
- Every player's ships operate in Id order, so players can easily predict their own operations.
- All 11 players' sequences are intermixed randomly.
To make it a bit more plastic: PHost first sorts all ships onto 11 stacks, as if it were sorting a deck of cards. Then, it repeatedly picks the first ship from a randomly-chosen stack, until all ships are processed.
When ships compete for a global limit, per-player Id order chooses between all ships that want to do something (for example, in mine laying). When ships compete for a resource at a particular position (like in Rob or RGA), per-player Id order selects ships at every affected position.
