XD (next reply will be later visiting my grandma in rehab) so first give me a couple of times in the manga when this was used
Lee vs Gaara
Lee went from 3rd Gate to 5th Gate, without passing through the 4th. Meaning we can apply this technique at any point of the gate release. I mean, it doesn't matter if we have already oppened a gate or haven't openend any yet, we can still jump through some gates.
Guy vs Kisame
Guy oppened the 6th Gate directly, aiming to reach the 7th. That gives us the idea that the opening of more than one gate at the time isn't limited to jump through only one gate ( Lee: 3rd -> 5th (Jump through 4th)). It also gives us the idea that we can't leap through the 6th gate, the 7th gate, and the 8th gate.
