Emerald Garden Ascent - Challenge

Has anyone been able to actually complete this on the challenge difficulty?

Just finished it with a time of 79+ seconds after many, many attempts--and well above the 66 sec required for gold. The way I managed to get through the first half was using Skyward Ascent (space bar) for my boosts instead of Surge Forward while following a kind of a rollercoaster pattern between rings. There were a couple that I barely managed to drift through before getting enough vigor to bounce to the next ring.

Follow-up: managed to get gold by tidying up my route and the timing of Skyward Ascent to launch into upward arcs for maximizing vigor. It's definitely possible, but took me a lot of retries--normally I'd give up on stuff like this, but rn I desperately need Dragon Isles Supplies.
