I don’t get why people make up power levels, it was sgood until I saw the androids as strong as Gokus confirmed base vs frieza and frieza literally states in his second form his power is over 1 million why is his 4th form so weak
ITS OVER 9000!!!
Random numbers - go!
The ssj math is wrong. The multiplier is x50 or x60, so 1 million power is wrong.
My man thank you SO much for being such an amazing teacher! 🙌
Everyone knows Popo is by far the strongest. Lol
Thank you for sharing the videos. keep going and I'm purely subscribing to your channel just for leet code problems in python.
7:25 world 2 towers: ima head out see ya
I don't understand why you put Temari and Kankuro above Neji and Rock Lee after the Chunin Exam and also at the beginning of Shippuden
Rosinante 271 panels in 5-10 chapters ? How is that possible ? Or even Don Krieg 354 ?
I did not get the difference between the single and double brackets !
4:13 how in episode 99 Frieza was 2.4 million and S.s. Goku 2 million, but in ep 102 Goku has 1.5 million and Frieza 1.2 million
Also Trunks only 1.8 millions impossible considering he was far superior than Frieza
Just got through all of super. Can someone explain how Kefla is so high on the list at SSJ2? because she's fused? She's beating out golden Frieza you gotta be kidding me.. these chicks only just learnt how to go super Saiyan.
Well this is wrong. Frieza’s power is 1 million in his 2nd form, and his final form max is 120M. Goku hits 150M in ssj against him. You’re 2 decimal places behind.
This is terribly inaccurate
Jiren being at 200m when SSJ Goku in the saiyan saga was 150m moment
Very helpful content, thank you so much !
I like how even in super he does reasonable power scaling. Because most videos say goku base is 128B+ and uio is 4 septillion. This video feels more reasonable for some reason.
Where are the scouters when you need them...
Two big things, I noticed. 1. When was piccolo that strong through the frieza and cell saga? He was way too high for a way too long time up there. 2. Placing whis on 220m slightly above beerus with 200m and then later jiren and goku to over 400m+ is a little bit miscalculated... Whis will still be stronger than goku and jiren, even in their ultimates. I mean cmon, broly was no enemy for him, and he one shotted beruus one time to stop him casually.
Thank you so much. I kept trying a far more complicated method without success. I followed your clear instructions and voila .
Can you post the titanic data from the video so I can better follow along?
He does realize the 2nd form Frieza was stated to have a power level of over 1 million, but this guy listed final form as around 500k
And I have to mention first form Frieza had a power level of around 500k so this guy really didn’t know what he was talking about after the saiyan saga
Even 0.25x speed was almost not slow enough
Why would piccolo be stronger than goku and vegeta during the world tournament saga just before buu saga kicks in?
This is false friezas weakest form had 530k and his final form 6m and final form 100% is 130m base goku was 3m and ssj was 150m
No one is above Mr. Popo
Can't be right. In Raditz episode an ordinary farmer has a power of 50.
Well not an easy task, some mistakes the DB chart was good though
Thanks so much for this, I typically use SQL but have to take a CodeSignal assessment and Python is my best option. I've been watching so many videos and none seem to click but yours have. I'm going to go through all of your leet code examples and hopefully it clicks.
SSJ Trunks beat the shit outta Second Form Cell and is bellow him in the graphic.
It looks like those mobile idle games
How did you get the confirmed power levels completely wrong?
def getindex(n,lis): for i in lis: If n - i in lis: return[lis.index(i),lis.index(n-i)] Just reduced number of line
Why is everyone just ignoring how awfully inaccurate this video is? Pretty much every power level is wrong.
Its not that deep.
Why do people still watch these horrendously inaccurate power bar videos?
My boy Tienshinhan is consistent & underrated. What a legend!
"Either frieza hits me too hard that I'm in delusional coma or .. POWER LEVELS ARE BULLSHIT"
Thank you for your effort man real real helpful
thanks
You are an absolute legend! I got proud one day when I made a ln Excel database that crashed the PC, then someone showed me Access and I felt a bit ill. Can't be put off the "coding" fear any longer...
I'm a student of Computer Science Engineering, I have strong faith in my programming skills not because I'm a genius or something but because I don't take any module or lesson of coding lightly, I understand that every little explanation about the most trivial topics is an experience that cannot be gained simply by just skimming or thoroughly scanning it. Learn not Study, this that's what my middle school teacher taught me and that stuck with me, now I'm grateful that I can grasp and comprehend any language with ease just because I paid attention when I was younger
2:26 How did Goku get so powerful suddenly? That makes no sense
Idk about that. A lot of those powers seemed well off from what they originally are.
Power levels will never not be an absurd concept. One guy has a slightly higher PL? He can tank a huge energy blast. Slightly lower PL? He gets obliterated.
thank you
Hindu Temples (many over 1000yrs left the chat..) *Ranganathaswamy Temple, Srirangam* The Tallest Temple (gopuram) Is 236m --One can easily see the coast of Sri Lanka from the top of the gopuram. This temple is about 700 yrs old!! You guys only now how to include churches & pyramids but these temples are way older..
Love❤
Who else freaked out when Goku's power level reached over 9000?
If you are new to the series just a heads up power levels are bullshit
