I mean, Bell is good at running away. Bell was able to run away from a Level 3 Lefiya at Level 1, and the reason given was that he just knows how to run away. There's no point in speed, because even shortening the distance, it takes time to find Bell after he disappears around a corner, and he's just better at overcoming obstacles in his path than the others. That's how he escaped from someone 2 Levels above him. So even a high Level 1 Bell could probably escape from almost any Level 3 Amazon in Ishtar Familia, and a Level 2 Bell would do it guaranteed. His Level 3 status gives him a lot of room for maneuver, besides just getting faster than other Level 3s. So this case cannot be used as proof of his pure speed.
I've already said that I don't deny the fact that Bell wasn't in perfect condition, but that can't be used as a reason to disregard a difference like the difference between Levels. Yes, it won't be complete, but it will still be huge, and Bell didn't show that in any way in the fight, Aisha had no problem keeping up with him. There's a difference between having Aisha demonstrate that she can surpass his huge Agility advantage with other stats and experience, but the thing is, it's never even hinted that Bell was faster than her, meaning they both just had similar stats. And no, the Hyacinth example can't be used because Hyacinth clearly states that Bell was faster than him even though he's Level 3, while there's nothing like that in the battle with Aisha. At this point it just seems like you're trying to make up something that doesn't exist, just to fit the case of Phryne.
I don't recall any group of three Level 2 adventurers with G in their basic abilities making it to the 18th floor. But in any case, coming to the 18th floor and mopping up the 17th floor are not the same thing. Minotaurs can be encountered by the dozens, but they are rare occurrences. You can use items like the stink bag, or just avoid large groups of minotaurs to get to the 18th floor safely. And of course, you can't get too many stats in the early Levels, so when talking about stats being able to surpass Level sooner or later, I was talking about something starting at Level 3 or 4.
The case of Zard and Alfia doesn't fit. Empress was Level 9, and Maxim was stronger than her, meaning he also had at least Level 9 battle prowess, so that's a difference of 2 Levels, not 1. I read the spoilers for AR3, and it said that Riveria's Vas Windheim is able to surpass the difference between Levels when she at Level 5 almost kills a Level 7 monster, even though we know that even her Rea Lavatein can surpass a difference of 1 Level. So Omori writes about the three of them "can surpass the Level difference" as something very impressive, only when they surpass the 2 Level difference. That's not the same as a 1 Level difference.
Being able to keep up with someone is a case that is possible even with a difference in Level. I think you'll agree that even Level 5 can serve as support in a battle against Level 6, because he won't be killed immediately. Ryuu was able to hold off Ais for a few minutes, and Tsubaki can stand her ground against the Loki Familia leaders. Ais even faced off against Levis and could inflict deep wounds on her, though she was defeated in SO7. The fact that one Level 6 can fight shoulder to shoulder with another Level 6 is really nothing special. Even Aki could probably fight effectively at Finn's pace, let alone Gareth.
We don't know Luke's stats, and that's the main problem. Everyone who isn't a first class adventurer has a status that goes to B at best, but even that doesn't apply to all stats, only the best. The fact that Luke was claimed to be the best among the students of the School District actually means little within Orario, whose adventurers are named the strongest in the world. The students lack either experience or talent, a group of several Tier 2s can only reach floor 12, while a group of Morda, considered weak, can reach floor 18. I wouldn't be the least bit surprised if Luke's stats are in the 400 to 700 range, where 700 is just his Dexterity, seriously. This is definitely not the example of stats vs Level that I had in mind. Her winning at the same levels matters little as long as she's allowed to use magic and has a lot more experience than Luke.
Level 7 c Asterius could have given them a good fight, but Level 7 Levis was defeated by the same team in a matter of seconds. Admittedly, Levis like Asterius don't have experience comparable to a first-class adventurer, instead relying on their brute strength, so there shouldn't have been such a difference. My only theory: Asterius fought Tiona, Tione, and Bete, and his resilience (whatever that means) was enough that Bete couldn't move him much. At the same time, Levis was knocked off balance by Bete's kick, becoming open to Tiona and Tione. Although Tione only inflicted wounds on her, Tiona cut off her entire arm. In that case, the only factor that saved Asterius was being able to resist Bete's off-balance kick, which worked against Levis. Slightly unusual conditions, but it seems that the creature's mass did have an impact in this case, and there are questions about how many hundreds of tons Asterius weighs. Perhaps not a mass per se, but something of the sort of unconscious repetition of Ottar's movements that specializes in defense. Despite Asterius' admittedly lack of technique, Tiona and the others saw a shadow of Ottar in him, but there was nothing similar with Levis.
Bell think this when his Status actually refers to Level 6. So he's just confusing the difference between Level 5 and 4 and Level 6 and 4. The funny detail is that Bell always treats himself as a normal member of his Level, still not understanding his Stats.
It is not enough just to have a reaction speed higher than the opponent's movement speed, otherwise the faster one would be better than the more experienced one absolutely always, for he sees all his possible attacks. There are also such things as techniques and tactics that include blind spot attacks and reflex deception moves (Making the opponent think you are hitting with this punch, focusing his attention on it, but then throwing a real punch that the opponent is not ready for. Essentially just a deceptive movement). In the moment when Bell can't follow Hyacinth with her eyes, the technique is even explicitly mentioned. Even Juggernaut is stated as dangerous to Zard and Alfia simply because they have no information about him, but if they survive the first 20 seconds, they are guaranteed to defeat him, confirming that surprise is indeed an important factor in combat.
I've read spoilers from this this Wiki, so I'm fairly confident in what I'm about to say now. It was said that Finn and the others Leveled up right after the events of SO12, but it wasn't revealed until SO14. We didn't realize it before, but timeline suggests that Gareth was already Level 7 at the time of their fight. And even given that fact, we weren't shown their fight as well as the others in MS17, so it hardly matters.

As far as I know, Bell didn't adapt to the new Level and fought both at the same time, so it doesn't matter.
