The self-test results were okay, but I don't know what the score will be.
Based on this

AM -> AP-At (+Cross Less Often, Get Further Forward)
+ Stay Wider to BPD (Left)
BPD-De (Right) -> BPD-St (+Hold Position)
Based on this

IF -> F9 (+Stay Wider)
AFs were moved one space to the right
AF(Right) -> PF-At
BWM-De -> DLP-De (+Take More Risks, +Stay Wider, +Tackle Harder)

I am attaching the xG Table because I believe that luck had a huge impact on the results.
+ More Direct Passes to AF(Left)
BPD-De -> BPD-St(+ Hold Position, Stay Wider)

I also made a version that retained BPD-De and am considering whether to upload it as Man City's league performance was slightly better.
Both DM-Su -> RGA-Su
BPD-De -> BPD->St(+ Hold Position)
Based on this

+ Get Further Forward to DM-Su
BPD-St(right) -> L-De (+ Take More Risks, Stay Wider)
Both side BPD-De -> BPD-St (+Hold Position)
Middle BPD-De -> L-De (+Take More Risks)

Also tried CD-St or L-Su but they didn't work well
How about using stoppers?
Based on this
AF(L) -> PF-At (+Dribble More, Roam From Position)
Both BPD-De -> BPD-St (+ Hold Position)
original
+More Direct Passes to AF(L),IF(L)
+Take More Risks to both AF
+Roam Form Position to SS

forgot to append Tackle Harder to AF(L)
After combining this, I excluded underlap left and Narrow as advised by @dzek .
Looking at the results, I think someone should probably create a new version without HB.
The offensive line was changed here.
Attempts are being made to move the role of AF to RMD
Attempting an extreme offside trap
I think the 424 deformation's offensive form is the best, so I'm trying to settle it into a more defensively stable formation.
It's been a while since I've seen Luton finish 3rd.
Is the number of goals conceded a coincidence or a new discovery?
It seems likely that it was just lucky, but I'd like to see the results.
Trying to add more pressure roles.
The defensive role has changed here.
