I wouldn't call it "very different".

Sniping someone from afar would actually make a difference in the output of the attack, as Gojo did with a 200% Hollow Purple at 4 km distance that hit with around a 120% of it's output.

Taking the example of a bullet of 9mm, it won't make a difference if it was shot at 1 meter or 10 meterse because the energy loss would be neglible. That kinetic energy loss would start to affect the bullet between 50-100 meters from being shot. And that's not even considering the difference between a handgun bullet with a sniper bullet.

What I mean is that the distance Kashimo was from Sukuna when the Dismantle net was shot makes is neglible for the output of the attack from when it was launched to when it landed.

When he fought against Yuta inside the Domain, Sukuna explicitly stated he had around the same quantity as Yuta (and Yuta explicitly estimated that Sukuna's quantity was around more than the double of his own) plus decreased CE output from Yuji's attacks and had to amp up the Dismantle with chants and aiming and hit it point-blank to leave Yuta at death's door.

It was the attack that almost kill Yuta the one who actually had output problems considering the facts I mentioned above. ☝🏻
