I agree with the sentiment here. It’s not about how many calculations he is doing per se but how many different images he is using to do so. Despite USK only showing one pixel scaling image, he is “technically” using three different “panels” for his calculation of which it is possible for the position of the character to have changed during the transition from one of those panels (Full body Madara and Naruto to Naruto partial body shot) increasing the margin of error. Additionally, he’s also using a calculation from a “Panel” where the feat occurs to a prior “panel” where the scene doesn’t occur. As I recall, more “scans” in a pixel scaling = less accurate
On the other hand, Mex is “technically” only using two panels for his calculation in which it the only change between the two is the movement being calculated.
And finally, if you actually looked at USK’s calculation, you find that he used Mex’s distance calculation meaning his steps would actually be:
- Scale Naruto's full height to the distance between Naruto and the staff.
- Scale Naruto's full height to Naruto's face.
- Angsize the distance to the staff from the screen.
- Angsize the distance to Naruto's face from the screen.
- Find the difference between them, then use Pythagoras with a scaling of the length of the beam to Naruto's face to find the full distance.
Basically, he not only used more panels, he also technically used more calculating steps.
