2^365 days isn't usable here nor it will change the stats of Saitama until Monster HQ arc. Because we don't know at what rate he was growing each day after he broke his limiter.
We only know that he grows enough to one shot himself each day within the time when VGS happened and after, it wouldn't affect anything before that since they can't be valued correctly. And even Garou who broke his limiter, wasn't growing as fast as Saitama, it was the day he broke it. supporting this argument. Not just that but Garou himself stated that his acceleration was getting faster over and over after all. It'd be the same for Saitama who broke his limiter. Even we could clearly see the difference in speed of his growth by his feats(Garou).
At most it'd make 20-40 days since VGS(after Boros but before Gouketsu) since that's the earliest we know his daily growth level has reached these leves. Even going retroactively, His current value 5.6394e+63 / 2^40 = 5.12900442e51 which still suits his canonical strength within the entire series (him being strong enough to one shot the characters, suits it).
The graph itself is a statement here. Supported by
the martial art. In the same fight, It is
stated by Garou that Saitama wasn't capable of one shotting him at that level(Saitama being 2x stronger-or more-) there. While Saitama from VGS has a statement of one shotting himself via growth in a day.
Garou's stats are completely based on Saitama here, Same for VGS Saitama. Both fights are Saitama vs Saitama. Saitama from Garou fight can't one shot Saitama of the past while Saitama from VGS grew enough to one shot him.
He would be 3-B in 18 days after Monster HQ. He'd reach universal in 96 days after Monster HQ. It's not like this is wrong or anything though, Saitama and Garou has removed their broken and can reach any finite level of power over time. We also know they can grow tiers above their current level as well(Garou is shown to do it many times).
One shotting yourself after a day itself is an insane feat, no matter what, the result would be high.
I never said anything about using Garou and Saitama's rage amps level growth rate value.
Not sure why or how it breaks rules. As one shotting yourself after a day itself is an insane feat, no matter what, the result would be high.
The statements are already in-universe.
One shot statements,
the graph before Garou makes the statement of one shot,
the martial art. Both enemies are Saitama(One is Garou who's stats are Saitama's of a little before and VGS Saitama who's Saitama of yesterday.)
The statements are clear, the values are consistent with the verse. There isn't an inconsistency and it only applies to Saitama, Only after Monster HQ arc(After VGS but that Saitama is already weaker than the current Saitama by like His current value/2^30).
There shouldn't be a problem for this to be added. (Or possibly at least? It should fully be there though in my opinion)
------
That's all i guess... Sorry and thanks for everyone who bothers to read it

(because of the size).
Edit: If this is accepted, His Post-Balding version will get something around x2^7 , x2^14 (based on how many days passed since Monster HQ arc, which is around a week or two if irrc) and
Saitama's Post Training Accelerated Development section (
Saitama's strength increases drastically by the day). If not, Only
Saitama's Post Training Accelerated Development section (
Saitama's strength increases drastically by the day) will be applied
