Rule 6
"Cinematic time should never be used to argue that a character is faster or slower compared to speed statistics based on other feats."
A character, capable of dodging beams of light, is seen in a fight scene. The viewer is able to see him throwing punches and dodging attacks.
The fighting scenes here are slowed down so that the viewer can see them. A battle at light speed wouldn't be visible to the viewer (thereby defeating the base premise of an audio-visual depiction -_-). In such a case,
it should be assumed that the battle is slowed down at all times, hence it cannot be reasoned that the character is slower than his previously depicted speeds on this basis, aka, rule #6.
Rule 7
"
One should not assume that cinematic time is consistent in any way. Hence, calculating how much slower/faster cinematic time is compared to the actual time in the work and applying that to ratio to another instance is not a legitimate method to determine the actual time-frames in a piece of work."
In a scene, a beam of light is depicted traveling 3 meters in 5 seconds. Right after the beam leaves the field-of-view, we see a character moving 2 meters in 5 seconds.
Even if the events are right after each other, cinematic time doesn't have to necessarily be consistent in any manner. In the scene described, the movement of the character might not be depicted with the same perception time as the light before. In this case, rule #7 would come into effect.
EDIT: I went back and looked at those 109 seconds after the meteor enters the atmosphere and it's silly how much of it is cinematic time, we see...
- 42 seconds of Erza inner monologue
- 5 seconds of Fodder Dialogue
- 5 seconds of Irene Dialogue
- 21 seconds of Erza jumping up at the Meteor
- 36 seconds of Erza Dialogue where the Meteor apparently stops moving and is right in front of Erza's face which we see is going at an acceleration where she would get hit in 2 seconds, but she talks in mid air for 36 seconds, hence cinematic time
Basically, there we don't even see the Meteor for the majority of these 109 seconds, meaning that
this supposedly being real time is simply ridiculous
See how close the Meteor and Erza get close to each other, well this scene is immediately followed by 36 Seconds of Erza talking in mid-air, If this was all real time, then Erza would have no time to talk for 36 Seconds, because the Meteor would crash into her in like 2 seconds based on the acceleration they're going at in this scene, meaning that all this is slowed down for cinematic time, and therefore the 109 seconds should not be added onto the timeframe of the calc, as those 109 seconds are artificially there just to show what the characters are thinking in a brief moment and show us what they're doing, if this scene was done in real time, you would blink and it would be over
It should be fine to use just the 10 seconds it took for the meteor to come from outer space and ignore what happened after it touched down on earth. It doesn't have to be consistent, nothing in anime is ever perfect.
I agree with the OP that whatever follows the meteor entering the atmosphere can be chalked up to part of the story's cinematic timing since it's a battle situation and all that and can be disregarded.
Next thing you know, Borsalino's attacks don't travel at LS anymore
