There is no way in hell you can be as effective in your fourth consecutive plate game or your seventh consecutive game as you were in your first or after a break.

Unless you were "pacing" yourself from the beginning knowing that you had to work that many games on that day. If you were doing that, then you weren't effective from the beginning by not giving the game and the players your maximum effort.

As for your assignor....I have ran into plenty of assignors who seem to thing that umpires are a "necessary evil" of running a tournament and just look for bodies to put out there without regard to how it affects the umpires or the games.
