I don't think she was/is fading in the Prism era. The fact is that Teenage Dream era was obviously bigger than Prism. Is it hard to understand?

!

Yes, it was.

Saying that Prism is her peak is like saying that MDNA is Madonna's peak because she performed at the Super Bowl and her tour was bigger than those she did between the 80's and 2006.

Teenage Dream was her peak, point blank. But that doesn't say anything about her current success. She's still doing very well.

1)Gaga hadn't a biggest tour compared to the TFM ball tour.
2)Gaga hadn't biggest stat power compared to the TFM era.
3)I referred to another factors like streaming, radio where Gaga wasn't stronger compared to the TFM era.

Have a nice day.

So for Katy, sales and chart positions are not an indicator of a peak but they are for certain other popstars? Mess at the double standards.

Katy's album peak: Teenage Dream
Katy's single peak: Teenage Dream
Katy's power peak: Teenage Dream
Katy's relevancy peak: Teenage Dream

The only thing she outpeaked this era was the tour gross, but that's only because her first tour did so poorly.

Wrong, wrong, and wrong.

The BTWB played bigger venues, had an overall higher gross average, played in more countries, etc. The Monster Ball needed 200+ dates to gross $200,000,000. The BTWB gross $180m with less than 100 dates.

Gaga had her biggest opening for album sales with Born This Way. In addition, BTW went #1 for longer than any of her other #1 singles.

Your own logic goes against your fave. Katy was stronger on radio during TD than she was during PRISM so by your own words TD was her peak.

Have a nice day.

Fake.

The Born This Way Ball was bigger, it grossed 1.8 million per date and sold out stadiums in Europe, Asia and Latin America while The Monster Ball grossed 1.2 million per date.

Her star power was also bigger, she topped Forbes during the Born This Way era among other things.
