Do you have a vid of this? It might be useful to try and emulate.
I can make a vid if you would like, but my bombing wasn't anything special. I just tried to lay the last three bombs earlier than usual so they'd get under me more. I'd say the actual height of the jump was only just slightly higher than your VS trial 5 vid, where the top of Samus's right boot was even or just barely below the ledge.
And that's a cool Geo Core discovery... However, you would still think that the spinners have to be raised. I was messing around the other day with the first spinner, and the furthest up the pole I got it was three quarters of a rotation away from being all the way up. Has anyone gotten it further than that?
