The level of urgency is a hierarchy in itself. The idea is the have the urgency level that is easiest for peeing. When desensing at that level results in 90% confidence, you move up a level of difficulty by using a slightly lower level of urgency.

Guys who have paruresis are very familiar with bursting to go, and with trying to go with a very low level of urgency. They are unfamiliar with peeing with an intermediate level; hence the need to allow yourself to fill up to a comfortably full level.

Most guys on the workshops say that once they have gained confidence on the weekend, they find the higher urgency makes it easier.
