No Mentioning Events of PIS
Plot Induced Stupidity, or PIS, is when characters don't use their abilities or skills to the fullest extent as shown before, even within their personality ranges, for the sake of the story plotline. It makes lesser powered characters an actual challenge against higher powered characters in the comics. Examples of PIS include Flash stories lasting longer than three panels, or Toy Man as a threat to Superman.
Character Induced Stupidity, or CIS, on the other hand, refers to any natural mental limitations that characters impose upon themselves and reduce their ability to use their own skills and powers effectively. Unlike PIS, CIS does not occur because the plot requires it, but because the character is genuinely that dumb. Examples of the CIS-afflicted include characters such as Rhino or Jar Jar Binks. Events of CIS are not exempt from debates.
No SvFL
Spiderman vs. Firelord, or SvFL, is a shorthand that refers to any time when a character performs a feat that their powers and skills should be blatantly insufficient for, and is not repeated or is rarely repeated again relative to the character's overall established career, as well as the character's opponents' established showings. In statistical terms, it is an outlier, something that is radically beyond the character's established capabilities. For example, Spiderman defeating a herald of Galactus is a case of the SvFL exemption; however, Batman being able to sneak up on Superman is not because he has done so frequently under different writers.
For standard debates, feats considered to fall under the SvFL exemption are not valid. Likewise, examples of writing which go against firmly set canon are also ignored. For example, in Larry Hama's run of Batman and Grell's run of Iron Man, both characters were out of character and did things very much against established canon; therefore those runs are disregarded.
Wolverine often does feats well beyond what should be capable and accepted. My opinion is beating the Colossus, Hulk, Thing or Namor H2H is well beyond him.
