You still ended zone 4 deep, but not zones 5 and 6.
In zone 6 you were only a bit deeper than edge, not deep anymore (zone 5 you were deep).
Stay deep in zones 5 and 6.
If you go deep in these zones, you can always rotate early, keep an eye on the others, you don't get scuffed, and rotating is way easier than when you're edge.
