I'll note that it was fast enough to save his "precious student's" life and an argument from "it was lower limit" is quite fallacious. Saving one of his student's lives is hardly a "lower end" speed feat.

Then there's also the Naruto calc....
Which I should definitely systematically destroy. That calc has MANY more problems than the Gai calc. Seriously, I can't believe such stupidity is allowed to run rampant on OBD and those calcs left standing as "legit". It's as if no one there has a clear understanding of how real science or physics work and they just mash together concepts into freakish Frankenstein calculations.
Here are all the problems with that calculation:
1. Sasuke's arm is not swinging, it was stabbing: a stabbing motion is slower than an arm swinging motion. This is simple rotation physics: a swing has the arm almost fully extended. A stabbing motion has the arm bent at the elbow. The stab wasn't quite top down like the sword slices measured on Mythbusters so the benefit of gravity is not there to help the arm move faster. So even if the same exact forces are applied to moving that kunai as applied to a top-down swing, the arm cannot move as fast, at the very end, because it is bent (see forces applied to a lever arm, over time, in your physics 201 textbook) and semi-thrusting and semi-swinging in a rotation motion. Loss of length of lever arm? Loss of maximum speed. So an equal application of the Mythbusters swing fails here.
2. The mythbusters calculation measured 6ms to slice through 7 inches. They said on the show that they found 'the best'. I would take this to mean that they are among the best modern Samurai swordsman they could find in CA. Here's where the calculation goes horribly wrong: they measured the peak speed at which the SWORD moved through the bamboo bundles NOT their arm speed. They were measuring the blade speed. Because of how a lever arm moves in a rotation, the speed at the hands will be significantly slower than the speed at the tip of the sword. This is also a lever arm thing (like above) but it is rotational lever arms. This is known as angular velocity. The speed at their hands would be significantly lower than the speed at the tip of the sword...like...much slower. So in order to calculate the velocity at his fingers, you'd need to know the length of his lever arm and his velocity in radians. That cannot be determined from what we know. The use of this Mythbusters feat is not translatable, in a physics sense, to this speed feat from Sasuke because of points 1 and 2.
3. The speed of the sword, as mentioned in point 1, would be faster than Sasuke's stabbing motion because of the lever arm distance mentioned in point #2 and gravity assisting with the slicing speed.
4. The actual speed of the slicing motion was calculated wrong, as well.
7 inches in 6 ms.
7 inches = 2.54cm*7 inches = 17.7800 cm
17.78 cm/100 (to find meter) = 0.1778 m
0.1778 m / 0.006 s (this is 6 ms) = 29.63
29.63 m/s is the ACTUAL velocity of the swinging samurai sword.
So his math is wrong...and it is wrong against his favor. WTF?
5. Sasuke is taller than being portrayed by the measures. The blue segment being used to measure Sasuke's height is just wrong. Sasuke, in the first image, is standing with his feet apart. That can reduce his overall height. Besides the non sequitur use of his arms in the stabbing calculation, there is also the error in height that was used for the calculation. There's also the problem of him not standing straight up: his had is slightly hunkered. Then he is leaning slightly on his right leg. Using myself as a measure, I stood straight up (I'm 5'10"😉 and then stood with my feet shoulder width apart, with a lean to the right, with my head slightly lowered like Sasuke's. There was a 4.5 inch difference in height. Since Sasuke is shorter than I am, let's use 4 inches. That's 10.16 cm.
So the arm length measure now becomes different. Also, measuring with a rule on your screen is quite dumb/lame. The best measure, because it will be the same on everyone's computer, is using pixels. Just zoom in enough and count them. I am not going through the calculation, again, but 10.16 cm needs to be removed from Sasuke's height in the calculated speed feat.
6. Naruto was coming to a stop in the very next panel but was sliding mad crazy on the water (it's like he's skiing...just look at it). That means his final resting point was farther than the one where we see Sasuke. That will significantly lower the measure. Doing a visual, I estimate Naruto's distance to be about 3 meters away from Sasuke, at the most.
So what did we learn from this? 6 major areas of flaws that show the calculation not only has bad math but atrocious concept execution. As the variables stand, the feat is incalculable. We just don't know how fast Sasuke's stabbing motion was and we have no idea how long and how far Naruto was sliding on the water before we see that panel (look at the water streams...looks like .5 meters to 1 meter).
So the feat must be thrown out, in my opinion.
The best "base" Naruto speed feat we have is an actual second count down where Naruto closes the gap with Pain (Nagato) during Naruto's 5 second, on panel, count down. Why was that not used? I'll tell you why: it would vastly reduce Naruto's base speed.
This makes me wonder how many of the calculations in the wiki are either plain wrong or significantly off. I know with Edward's profile, they have his strength horribly under estimated. Edward says they are thousands of time stronger than humans (or a thousand). The average human male (in shape, not this modern sedentary version that we are, now..I can almost get 300 lbs, myself) can clean and jerk over 150lbs. Using a low end estimate of only 1000 times stronger, that means Edward can clean and jerk 150,000 pounds. That's 75 tons.
Why was that canon statement made by Edward, who is one of the most educated people in their universe (Edward said that the only person who has read more books than him is Carlisle and twilight vampires have eidetic memory (from book 4)). So why would Edward be a biased source or an inaccurate source? Based on the strength feat I calculated for his "tree pushover" feat, his strength jumped well into the hundreds of tonnes (not tons) of force, thus proving Edward's statement about "thousands" of time stronger to be accurate. That's just an example of one of the areas that OBD is definitely wrong with their calculated measures.

Hmm, Kishi once stated that modern firearms would be the end of the ninjas, hence why we don't see things like guns and missiles. Now, gunfire has never been able to actually seriously hurt Goku even in the first episode when Bulma shot him in the face.
Touché.
This makes me think that the ninjas are intended to be portrayed much closer to in speed to the measure I came up with for Gai: 44ms-88ms.
