I've seen this brought up in a lot of Spiderman threads and I'm wondering how the board feels about this. Does he truly have dynamic strength and if you feel as if he does, what showings make you think this?
I mean, he does in the sense that all comic characters basically do.
In the right circumstances almost every super hero is going to be able to lift/break/catch something bigger or heavier than their stats indicate they should be able to.
Yes he does by KMC standards. He went from not being able to defeat Firelord then dropped his mental blocks and rose above Herald level then wrecked firelord who has given Thor and Surfer fits.
I remember seeing an official bio that said that his strength can go into "uncharted territory".
As for actual in-comics feats I would say yes it is. And current Spider-man writers seem to fully acknowledge that. A little spoiler alert. In the recent ASM story we find out that Jackal resurrected Ben Reily and in order to prevent him from breaking free literally grew him into metal shackles that Ben was not strong enough to break. When Ben was telling this story to Peter he told him that in order to break these shackles that were too strong for him he tried to get himself in the Mood, the same way Peter "always used to do" in order to perform a strength feat he physically should not be able to do.

Or the time he said Phuck Physics and broke Ock's carbonadium arms. If nothing else, atleast Slott is a big believer in Spidey's dynamic strength under pressure.
Clearly, all superheroes have an adrenaline-like ability to dial it up a notch or two. But some seem to have this more than others. It's a spectrum.
That said, while Spidey might effectively be more dynamic than others, I wouldn't say it reaches the point where we'd include it under the 'dynamic power' label. Few qualify as such.
