Off-tempo

When performing off-tempo, it means the pace or movement of your tactics are out-of-sync with the general events, desynchronised and generally erratic. An off-tempo individual is more likely to make mistakes than an on-tempo individual and often loses the flow of a given battle.

The opposite to an off-tempo movement is on-tempo.

As a confusion tactic
Off-tempo strategem is valid tactic as a confusion tactic as it prevents your opponents from figuring what sort of pace and momentum you have, or where you will engage next.

However, realistically, tempo momentum should be towards increasing momentum as off-tempo strategem allows for openings if identified.
