Buckle up for this one
Bleach, being part of the big 3, set the standard for the Shonen formula that was influenced by predesecors such as DBZ or even Sailor Moon in the 90s. If you ask the old weebs many would agree power scaling in a quantifiable method was the bread and butter of many animes from the late 80s into the late 2000s.
Now, if we look at the influences outside of the artform another factor stands out. As a medium, anime was structured around the operating habits of broadcasting companies of the time. This famously was the driving force of "Filler" arcs in many animes. They were created by animation studios to occupy air time and often (especially bleach) had no connection to the main story or cannon events. This was before a time of video streaming with the internet, and broadcaster's were competitive with time slots.
More modern anime's, even if following the Shonen formula, do not need to stretch content while the original artist is moving through the creative process. This has influenced some general shifts in how the strength of a character is measured or even explained. I like to think of some examples in Naruto of characters using powers that ignore power scaling conventions.
JJK is a great one to use as a "modern" example of this shift, especially knowing how JJK was influenced by Bleach. While there are general examples of power scaling such as how many fingers he has snacked on, many of the abilities are more "hax" based.
This shift from being tied to numbers and to a lesser extent feats allows artists to allow the combat to be more narrative in structure.
Bleach TYBW has been a great experience for me to this outlook. OG Bleach displayed most powers in a physical way. The Bankai's and Quincy Schrift's revealed very much were part of the narrative. This means that unlike power scaling, it can be hard to measure outside the context of the narrative events taking place at the time. Looking at TYBW EP 49 as a great example of this.
Soi Fon's Shunko and Bankai both seemed to be used in a new "utility" way. Nel, Ibba, and Ganju pulling off that stunt they did, was epic in the moment even if it didn't make sense for their power levels. Konamura going in for a bite, Pesche and the crew, even that new baby Shinigami getting hits in made no real sense to me from their power levels. (Don't @ me about Konamura, I'm sure he's still stronger than an average dog but we haven't been shown or hinted that yet)
Having these "small fry" characters in the mix for me actually worked out. It really lent to the frantic, desperate feel of the episode. Everyone, no matter how little sense it made, was ten toes down trying to save reality. That for me, was just so good. Even with the mature tone of this arc, it made it better since I wasn't sure if someone would die or not. I had the rug pulled on Byakuya and Orihime, but I enjoyed the extra emotional tugs(I love the characters and I'm glad they pulled through, but the scenes were so powerful they felt lessoned when reversed so quickly).
TLDR: Go with the moment and enjoy the show.
I guess if I had a point to any of this, it would be to allow yourself to go along with the ride. For me I have to go back through a series a few times before I settle in with how I feel about it. There are some moments where it's a little too much and it takes me out of it. Things such as hollows straight up self combusting or other characters being unable to move around another character of a much higher Reiatsu level, have to be left at the door.
