Reduced slowdown in landing

What's the key for reducing slowdown like in nfs_longjump? I have been told you have to tap duck while landing but also that you have to doubleduck, so which one is it?

It works pretty much as a bhop, but you make it with duck. If your scroll timing is bad, it will result in you getting less slowdown, just as bad bhop timing will give you less bhop speed. Perfect timing and you will loose very little speed.

It works in two ways. Either hold duck/Ctrl while you are in the air and release Ctrl just before touching the ground and make a doubleduck/scroll, or simply just doubleduck/scroll, without holding duck in the air.

I don't know which is the fastest, but on shorter jumps I would think it's faster to just scroll when landing. If you hold Ctrl in air before releasing it and scrolling it will take you more time to reach the ground and perform the doubleduck. And doing it this way on 10 jumps will loose you some time.

I scroll 11 times, every single time I do it. That helps me. Because I deserve it.
