Backward Momentum

Backward Momentum (abbr. bwmm) is a technique that allows the player to maximize the potential of a given momentum.

A basic strat optimization principle is to maximize the player's forward speed at the end of the provided momentum. This can be achieved by walking off the back of the momentum, followed by a forward jump.


 * On some setups, multiple executions of this technique may be needed to fully maximize the momentum's potential.


 * It's possible to calculate an upper bound for the jump distance, by considering the maximum speed at which the player can start without overjumping the momentum. It's impossible to gain arbitrarily large amounts of speed with this technique.

Momentum Threshold is something to consider when elaborating a strat: it can either be helpful or detrimental, depending on how the velocity is affected.

In any case, it usually makes optimization a difficult problem.

When a backward momentum strat involves turning back and forth, it is called Loop Momentum.

For real time parkour, consistency is key. Therefore, no-turn strats are preferred, though experienced players have started using loop momentum.

Here is a list of optimal bwmm strats (TAS) for short momentums:



Common 1bm Strats [wip]
Backward momentum has originally been created to solve the 1bm 4.375b jump (first with 3bc momentum, then with no ceiling).

This has sparked a search for optimal 1bm strats: The most well-known 1bm strats were force momentum and c4.5 timing, but as it turns out their efficiencies really pale in comparison to bwmm strats (though they are still quite useful for most jumps, especially considering they are easier to setup and perform).

Below is a list of common bwmm strats for 1bm:
