# Aim time

The time the aiming circle takes to shrink by 60 percent of its width, not the time to become fully aimed.

Also known as aiming time, gun aim time.

This is the most misread number on a tank. A quoted aim time of 2.1 seconds is the time for the circle to lose 60 percent of its diameter, so a gun that has just bloomed hard is still settling well after its aim time has elapsed.

Full convergence takes roughly twice that in practice, and how long it actually takes depends on how wide the circle was to begin with, which is set by [bloom](/glossary/bloom.md) rather than by aim time.

That is why aim time is read together with the [dispersion](/glossary/dispersion.md) penalties: a gun with a poor aim time and gentle bloom starts closer to aimed and gets there first.
