The built-in "static" schedulers (Perfect-N and Lane Rotation) will ensure that every racer will run in every lane of the track and will do so an equal number of times. This is so no one can complain that the reason they did not win a trophy was because they drew the "slow" lane. Whether there is a slow lane in actuality or not, people always perceive there is (even with a brand new track).
Have you already done what you can to be more organized so you can crank out the heats quickly, instead of trying to decrease the number of runs for each racer? See this FAQ for some tips on getting better organized.
However, you do have a few options to run racers in fewer lanes than you have on your track.
- Don't use some of your lanes. Just because you have a track with X number of lanes, doesn't mean that you have to use all of them. Personally, I think it is a waste of money to get anything more than a 4 lane track. Much more cost, harder to store, harder to setup, harder to transport, and leads to a slower race (more cars to pre-stage, load to the track, and retrieve). Besides, for the slower racers, it feels worse going up against so many more cars and being in the bottom half of a heat, than being in the bottom half of a heat on a 4 lane track.
- Run a Dynamic schedule. You basically build the schedule as all racers complete a run. Each run down the track for all racers is a "phase". At the end of each phase, the software will ask you if you wish to start a new phase. Stop after the desired number of phases. A Dynamic schedule is a slower way to run a race as opposed to a "static" schedule like Perfect-N and Lane Rotation, since you build the schedule one phase at a time.
- Build a custom set of schedules that you can then import into the software. Each schedule file will represent a certain number of racers. After your check-in is complete, import the schedule corresponding to the total number of checked-in racers.
In the end, we believe that Option 1 is the best choice of these, so you can avoid the "slow" lane argument as everyone will run down all lanes of the track an equal number of times.
