I was aiming for 3.4 billion and somehow managed this, complete with a successful Kaguya 4th last spell supergraze on my first ever in-stage capture of the Lunatic version. I thought it was worth a video.
Interestingly I also failed some phases I normally capture, like the stage 1/2/4 last spells, various parts of stage 5, and Tewi's second phase. I'd have restarted from failing Wriggle's last spell if it weren't for the over 11000 time orbs (normally 10000 is pretty good, 9000 is acceptable, under 9000 is auto-restart). But I did get unexpected captures of Remote Rabbit and Buddhist Diamond, so I guess that sort of makes up for it?
