I went to look at the scene I vaguely remembered but Spiderman never webs onto CM. Instead though, and I'm sure it's just inconsistent across the feats, but during the End Game fight even Thanos didn't react to lightning when CA fires from the ground.
The lightning jumps to his hand before he's thrown up a block. I honestly don't know if this is just Thanos tired or CA got way faster lightning. So I can see the Hela calc being more easier to scrutinize.
On the other hand, Electro's electricity calc is using just the mach 1 speed for the low end. And since we're big on speed being demonstrated as a special thing like QS or Makkari, this scene is the definition of higher speed being demonstrated to convey to the viewer what's happening is incredibly fast no? How else do we explain Spiderman's webs reaching several meters before the electricity lands? An outlier is arguable but like others have probably mentioned, there's many higher level speed feats just as there are antifeats. There should be some middle ground than an outright disqualifying of higher end feats. Not sure what is best but I figured I should point it out unless others have already.
