For the record, I calculate the grade to be an average of 5.3%.
My car - likely heavier than yours - needs around 5% to sustain about 60 mph while coasting (engine on).

If you keep it in gear, I'd expect it to add fuel on the lesser grades and engine brake on the steeper ones.

Any chance you can run downhill in neutral without reaching too high a speed ?
Maybe by starting the rollercoaster ride slower.
