You can have an impact on these type of decisions by agreeing to be a task adviser at the contest, or by lobbying the task adviser for your class. What the pilots at the contest want, and don't want, is usually taken into account when making tasking decisions. The weather forecast is usually the deciding factor in the decision to use the one point MAT. Most of the CD's that I have worked with listen to the task advisers, and the weather forecaster before concocting the days tasks, and most really try to call a variety of tasks. There is no external mandate to call certain types of tasks. Devising the different tasks is not as easy as would first appear once you participate in the process. Then there are some days when the CD's title needs to be changed to TEO "The Evil One."
