Furthermore, there are a few ground actions that also have this property. If Mario can then leave the ground without overwriting the stored vertical speed, he can effectively reactivate his speed gained prior to landing.<ref>Vertical Speed Conservation: https://youtu.be/6md3RA8bH40</ref> | ||
== | ==Timeline of a VSC== | ||
There are three parts to a VSC: When the speed is preserved upon landing, when the speed is maintained on the ground, and when the speed is reactivated in the air. If a positive vertical speed is stored properly, Mario can gain precious height while being in a freefall state, allowing Mario to grab onto ledges where a [[dive recover]] cannot, or using the [[misalignment]] of a corner to ground pound onto the floor. | There are three parts to a VSC: When the speed is preserved upon landing, when the speed is maintained on the ground, and when the speed is reactivated in the air.

Many actions will reset Mario's vertical speed to zero when moving on the ground, such as walking, running, and crawling. Jumping will override the preserved value with a new one depending on what type of jump Mario is performing.

A dive recover has an initial vertical speed of 30 that decreases by 4 on each frame, resulting in a maximum of 26 vertical speed that can be stored if Mario lands on the first frame of a dive recover. This is called a VSC26 (having 26 vertical speed conserved). | ||
It is | It is positive vertical speed that gets used more often, since it is more desirable for Mario to be moving upwards, but it a lot more difficult. Additionally, Mario cannot encounter a ceiling, which would cancel his movement and reset his vertical speed to zero. Nevertheless, Mario can land with positive vertical speed stored by dive recovering on the following: | ||

The maximum height a dive recover can ascend onto is 156 units up when using a normal edge, and 206 units when using a misalignment.

In comparison, a VSC26 can ascend onto a platform 247 units high with a ledge grab, and 274 units using a ground pound into a misalignment. Furthermore, if a star is involved, the combination of a dive recover and a [[Star Dance Clip]] (SDC) can reach 298 units up, while the combination of ground pounding and SDC allows Mario to get onto a floor 345 units up. | ||
