A lot of people speculated that Luffy mixed G3 and G2 when he attacked Yamato. Visually at least, it seemed that way.
But is it confirmed that she essentially blocked a Red Rock? Let's not forget an Elephant Gun grounded Zooan Kaido too.
This is grounding Base Kaido but also doing some damage too. I don't think Red Rock is that much stronger than EG tbh.
Maybe a 2-3x multiplier? If so I could see Oda having already revealed Red Rock.
