I will be doing a simple calculation on Revan's speed via the quote "AS MEETRA AND SCOURGE BATTLED the Guard, Revan charged toward the Emperor. His opponent stood perfectly still, focusing and channeling his power. At the last possible instant, the Emperor unleashed a wave of energy that swept Revan off his feet and sent him flying backward."
The size of the throne room Revan covered is "at least forty meters long" where the the throne chair was "at the far end."
Though it is unknown the time in which Revan completed the charge alone, the battle itself is said to be: " of only a few seconds."
The battle consisted of the following:
1. Revan charging the Sith Emperor (what we are calculating)
2. The Sith Emperor pushing Revan all the way backwards
3. Revan now moving more slowly towards the Emperor
4. Revan unleashing a telekinetic blast that through Vitiate back
5. Vitiate unleashing 4 lightning bolt attacks, all Revan blocked/dodged
6. Vitiate summoning a FLS while Revan calculates his options
7. Revan being blasted by lightning as Vitiate "pours" it into him
8. T3 spraying The Sith Emperor with a flamethrower
9. The Emperor blasting T3 to pieces
10. The Emperor walking over to Revan's lightsaber, picking it up, and going to strike down
The term "few" applies to 3, so ALL of that happened in 3 seconds. That being said, Revan charging Vitiate would be a complete minimum of .4 seconds. However, keep in mind at the end of the battle Revan was quite far away from Vitiate, and Vitiate walked over to Revan with "calm, purposeful steps." This alone, with all generosity, would have to be at least a second, especially by how it is said he "calmly" picked up Revan's blade. Vitiate had to of at least covered several meters in this time.
So Revan's charge would have to had been in a complete minimum of .33 seconds, right?. Nah. Keep in note that the time spent with T3 moving, attacking, Vitiate protecting himself, and the destruction of T3 had to take at least a second if the debris even had time to land. We seen in KotOR cut scenes how fast T3 moves, and it is no faster then a walking pace of a human, aka Vitiate calmly walking to Revan. I'm labeling this with a second as well. No objections? Good.
With what we have left, we have:
1. Revan charging the Sith Emperor (what we are calculating)
2. The Sith Emperor pushing Revan all the way backwards
3. Revan now moving more slowly towards the Emperor
4. Revan unleashing a telekinetic blast that through Vitiate back
5. Vitiate unleashing 4 lightning bolt attacks, all Revan blocked/dodged
6. Vitiate summoning a FLS while Revan calculates his options
7. Revan being blasted by lightning as Vitiate "pours" it into him
That is still A LOT of events that occurred in a matter of literally one second, since we already took off the two seconds via the events above. And now let's be honest with each other, Vitiate summoning that FLS, and then literally being said to have continued to "pour" Revan with lightning is with the complete minimum a half a second, and I am being extremely generous here. With that being said, and dividing the other parts nearly evenly (however some tweaking) because I am just that generous, Revan would have had to of covered that ground in .085 seconds.
Covering 120 feet in .085 seconds equates to 430.30 m/s. This time is actually no where near "ridiculous" as far as high-tier calculations go. Darth Bane's speed feet was recorded actually quite higher then such, then again it is probably the greatest speed feat in the mythos. Regardless, around 430m/s is incredibly fast, and hopefully will give Revan some more respect.
