The wait for a score keeper.
All things equal time.
Must have been the times I played in Louisville because there was time wasted.
More in Chicago about the same in Texas depending on when I played
Karl Deangelo of So Cal wrote some amazing software that addresses this. It uses tablets. The next player is automatically shown on the tablet as well as an overhead projector display. Entries are all managed electronically so once you queue up a player the entry is debited from their total. Scores instantly go into the system - no handling paper entries with chicken-scratch hand-writing. Extremely efficient and easy for both score-keepers and players alike.
As examples, when I helped score-keeping at CAX and INDISC, I was easily able to cover about nine games, which was about half the total. Same tournament in the previous years, I could cover 4 - 5 games, plus you need someone full-time at the computer entering scores from the score sheets. Since volunteers are paid in entries, the more volunteers needed the more it affects the prize pool.
The problem with allowing multiple plays per turn is a 5 player line just turned into possibly a 10-player line. That means players are more likely to wander off and need to be tracked down, or just balk and go do something else. You also open up the possibility of players camping at machines late in qualifying to prevent their opponents from getting a shot.
