First of all, that's a visual representation based on Tsunade's hypothesis how FRS works.
-Tsunade never saw the technique. She is merely describing the effects from a medic's standpoint.
-Visual representations can be outweighted by
feats and canon statements
-Even if Tsunade's standpoint is 100% correct, and the microscopic swords are not hitting at the exact split second it's important not to overlook the fact, that the blades aren't far off from each other to say the energy isn't being added up.
For several reasons.
-FRS isn't just a needle attack technique. It's explosion + Futon chakra(wind blades). Futon chakra boosts Rasengan's destructive power, it doesn't simply convert into needles altogether. Only the shuriken spiral is converted into needles, which all add up to the total energy in a compact explosion.
Adding "Wind" "nature manipulation" to the Rasengan, already boasting tremendous destructive power
-KidGamer65 gave a good example referring to Shin Senju punches vs PS. It's the same reason why 12 biju dama blades can destroy a portion of Shin Senju, despite 1 biju dama failing to destroy an inferior base construct such as Hobi.
-1 needle alone has no where near the energy of COR. Kurama could repel the energy

, yet the

of 20+ COR (added up onto each other) sent him flying. While something even stronger, the FRS pinned him down. [

Given several feats, how net force works in Naruto and real life applications, it's completely absurd to state that 1 needle is the total energy FRS is spending to breach a defence.
And most importantly, Kakashi description in the same page refers to FRS as
Attack Density rather than REPETITION. [

If the blades are dense/concentrated on the target it means the energy is being added up together. I’m not a genius at Physics but by common sense and science: If you push a box in one direction with 20 N, and your friend pushes the same box in the same direction with 35 N the force applied to the box is
the sum of both forces yours, and your friend's. Even if you push in different directions the force
both of you are exerting is being received to one spot, the box itself.[

All in all, it's very inaccurate and it really makes 0 sense to say that the attack is not concentrated or the energy of the countless blades isn't being added. For 2 major reasons:
-If all the blades energy wasn't being added up that would completely make the technique useless, when you could accomplish the same with less blades.
-Jiraiya describes the original Rasengan as highly concentrated, while Kakashi describes FRS blades as a concentrated attack rather than Attack repetition, which is a direct statement that the total energy from all the blades is being added up/
concentrated in one target or point.
