I've noticed that some calculations within the Mashle: Magic and Muscles universe contain certain flaws. I will present arguments for each of them and demonstrate my own improved calculations, correcting the issues I identified.
1 – Dot intercepts a stone head
The original calculation related to this scene shows some inaccuracies, particularly in the reference points used. First, the character Rayne’s height was assumed to be 1.70 meters, but his actual height is 1.75 meters. While a 5 cm difference might seem minor, it can significantly affect scaling.
Moreover, the original calculation used a stone density of 2,550 kg/m³, based on a website that is now offline. For greater reliability, I used a more consistent value of 2,800 kg/m³ for stone density.
With these corrections, the Attack Potency increases from 9-A (Small Building level) to 8-B (City Block level), and the Lifting Strength moves from Class M to Class M/G.
2 – Mash throws a giant scorpion
The original calculation, was based on cubic proportions of a generic black scorpion. However, the scorpion Mash faces resembles more closely an Emperor Scorpion and is visibly much longer—implying a significantly higher mass and, therefore, a much more impressive throwing feat.
With these revisions, the Attack Potency increases from 7-C (Town level) to 7-B/7-A (City/Mountain Level), and the Lifting Strength upgrades from Class T to Class P.
3 – Mash throws a buffed giant
The original estimation places the giant at a little over 300 meters tall, based on a tree. However, I believe this figure is underestimated, as the giant makes the entire school arena look tiny in comparison. Instead, I based my scale on the arena walls, which give a clearer sense of the monster’s massive size in that panel. Additionally, I included the mass of the chains for more accurate results.
With these changes, the Attack Potency increases from High 6-C (Large Island level) to High 6-A (Multi-Continental level), and the Lifting Strength goes from Class E to Class Y.
4 – Mash pushes a continent
This calculation contains more flaws than the others. The original estimate for the continent's mass was 7e18 kg, based on a YouTube video—but that value is drastically underestimated. I took a more accurate approach: I calculated the area of the continent using the arithmetic mean of all real-world continents, multiplied it by the average thickness of the continental crust to obtain the volume, and then applied the typical crust density of 2,700 kg/m³. This method provides a much more solid and realistic estimate.
As for the speed, I agree with the idea of using Innocent Zero's Thirds Sphere as a reference. However, Mash moves beyond this sphere, and the size of the sphere itself is underestimated. It’s explicitly shown to be relative to the Earth's curvature, indicating a much larger diameter. This results in significantly higher scaling for both the sphere and Mash’s feat.
With all corrections applied, the Attack Potency jumps from 6-A (Continental Level) to Low 5-B (Small Planet Level). I’ve also added Lifting Strength, which is Class Z/Y.
Based on everything presented, I propose a major update to the calculations for Mashle: Magic and Muscles.
Thank you for your attention.
