Storm I: DanMachi

The conversion of Falna Points, or the total value of all stats layer by layer except magic, will show a person's power level.

I think this calculation of mine is very close and realistic.

Example:

Name: Bell Cranel

Level: 1

Strength: SS-1,091

Endurance: SS-1,019

Dexterity: SS-1,098

Agility: SSS-1,337

Magic: SS-1001

Falna Power Level: 227.25

All status except magic is equal to 4,545 Falna Points. Next, get the 5% which is 227.25. And since the average power level for humans is 5, let's say Bell has 4 as a base, and then add the points together, making it 231.25

And each time they level up, the FP stacks up by layer which also has a bonus of 5% increase from FP stacks.

Name: Bell Cranel

Level: 1→2

Strength: SS-1,091→I-0

Endurance: SS-1,019→I-0

Dexterity: SS-1,098→I-0

Agility: SSS-1,337→I-0

Falna Power Level: 227.25→454.5

Total FP: 4,545

FP Bonus: 4,545 × 5% = 227.25

Total PL: 458.5

Next

Name: Bell Cranel

Level: 2

Strength: SS-1,088

Endurance: SS-1,029

Agility: SSS-1,302

Magic: A-883

Falna Power Level: 454.5→680.15

Total FP: 9,058

Total PL: 684.15

That's all. Each time they level up, they get 5% of the Total Falna Points they've accumulated in total which will be added to their total strength as a barrier for each layer of Level.

And they don't get their base power to increase because it isn't a part of the Falna.

Also, even if they have high power level, if they cannot properly use Ki, they cannot do things like Flash Steps or some movement techniques that uses Ki because Adventurers don't know how to use Ki except few individuals and do feats like obliterating a Goliath with a roar.

When it comes to Magic, it is the same as the power level scaling system from above.

That means he can defeat Ryoumen Sukuna at his full power, though they will be equal with Sukuna being a curse user and a strong person while Silver can literally obliterate a Yellow Star.
