Boil Release Unrivaled Strength is just a name, made evident by the fact that it didn't hurt Kaguya, it just pushed her. Much like the many techniques/items that have been called the "ultimate defense" that were ultimately broken.

Naruto didnt suffer any physical injuries and Shikamru said that she infused him with her chakra.

You bring up the databook which reminds me that one of them specifically stated Sakura was on par with Naruto and Sasuke accompanied by the panel where Sakura stood with KCM1 Naruto and EMS Sasuke. This idea is backed up by the couple chapters where her seal first appeared.

As fast as Sakura is, i think Naruto and Sasuke out-speed her.

If we apply Newtons 3rd Law then Sakura has nigh-Kaguya level durability. Coupled with her healing, Amaterasu or attacking her chakra network with Rasenshuriken or possibly Tailed Beast Bomb.
