goal difficulty

Quick Reference

A measure of the probability of a performer not achieving a goal. Goal difficulty is usually expressed as a percentage. Research indicates that, as goal difficulty increases, so does performance, up to a critical point, thereafter performance decreases. The critical point varies, but some evidence suggests that it lies around the 70% difficulty level, therefore goals that are only 30% achievable should produce the best performance. It is generally agreed that competition goals should be set at a level that performer expects to achieve about 70% of the time during normal training.
