If One Piece was a 10 before Wano, after Wano it's a 1000

Other series outselling One Piece does not have to mean One Piece lost popularity, it could mean that those series were way more popular relative to the series going on around Marineford, which as far as I know is true, since Demon Slayer sales were an anomaly
Like I don't know what series were going on around Marineford but let's just say there was Naruto, One Piece, and Bleach
Say that during that time,
One Piece sold an 8
Naruto a 6
Bleach a 7
Well, during Wano,
One Piece sold an 8
Demon Slayer sold a 20
And other popular series sold an 11 or 12 or something
Other series outselling One Piece does not mean One Piece declined, when the sales statistics of those other series are an explosion and an anomaly, it just means those other series are way more popular than the "other series" were during the time of Marineford

For example, Demon Slayer sold over 220 million copies, with only 23 volumes, over a period of 9 years, with running for only 4 years, with a pandemic and a very high quality and popular anime happening at the time when the manga was ending
