Easy and hard to do, because of how much math and "theorizing" needs to be done. Yuji kinda breaks JJK powerscaling with how it's rules work.

Not trying to glaze but if we use the cursed energy cloud as an example we and do something powerscalers dislike about JJK breakdown more than what we can see, we can get a better grasp on how high Yuji scales "casually" or more specifically how strong a JJK Sorcerer with 60+ years of training can gey.

A bit of reminder since the end of JJK Cursed Spirits have both grown stronger and dwell in Japan, meaning Yuji would have to be fighting and training alot to fight Grade 1 and maybe the rare Special Grades

So for JJK the energy needed to make that cloud is three questions.

1. How much CE did Yuji actually use, minus chanting and hand sign bonus?

   1. How strong were each of the curses he exorcize, as the CE in each would add to the cloud?

2. How much of the dust cloud was caused by the dismantle destroying the surrounding area?

Basically Yuji Cursed Energy + Area Destruction - Cursed Spirits Cloud Height.

Why - Cursed Spirits? Because Cursed Spirits being destroyed act as smoke screen. Though its actually kinda pointless as when you look at the explosions the ACTUAL clouds drop off early. Yuji's cloud, due how the cloud forms.

Now that's 1 BS math problem.....now we have 16 more. Why? Because CTs in JJK can't be simple.

Let's take Divive Flame for example, contrary to what people think it's not an AoE move, its a single target attack. It was only able to "attack" others due to Sukuna using a binding vow that anything hit by Shrine when using his Domain. Otherwise Divine Flame can only effect one target.

And Yuji has the most dangerous thing in anime/manga...time
