It's an interesting rule to assign to pacing related to conflict when writing.
However, it assumes that conflict is the only thing that is contributing to pacing in the scenario, which is almost never the case.
Consider the other contributing factors:
Time skips, character developments and relationship forming, obtaining an item, exploring an area/gaining knowledge, monologues and info-dumping etc.
For instance, if on one page, two characters meet for the first time and are cautious of one another and don't show any signs of trust, then a couple of pages later they act like best friends without seemingly having shared any major experiences or facing an ordeal together or even sharing advice... it speeds up the pacing (often detrimentally - I'm looking at you Star Wars Epsiode VII...)
Even Deus Ex Machinas and other Deus Ex's can increase the pace by forcing conclusions to things or forcing scenarios in early.
But really, a story should have a flow and the pacing should follow that flow and enhance it. During combat, you most likely want that pace to increase to create a sense of urgency and dynamics. However, in the lead up you may want to slow things down by taking a look at inner feelings of both parties and after you may want to consider the consequences of the skirmish.
A story that is just one fight after the other with no real weight behind the conflict - no build up, no aftermath, no emotion or anything ends up being rather boring a lot of the time (Bleach, Naruto, probably 1000s of others...). Even within a singular conflict, if a punch seems effortless for no good reason other than lazy writing then what's it actually contributing to the story. But if you slow down the pace just for a moment to show that they are putting their entire body behind that punch and it's putting strain on all their muscles and it's tugging at their heart-strings... well then, in that moment, during that fight where you picked up the pace, that punch means something.
Writing is a balancing act with these kind of things and I would recommend writing what comes naturally rather than assigning formulae and rules to avoid stories becoming one dimensional.
