You've got it, Toyota. Once you have the technique dialed in, the fact that you're getting more significant air time right now just means you'll be able to (i) increase the weight or (ii) pull harder (which has the same effect). With lighter weights right now, you'll have to pull "less hard" to only come the requisite "fraction of an inch" off the ground. Once you start adding weight, the heavier weight will take care of that for you pretty quickly.
Thinking about the second pull as nothing more than jumping with a barbell in your hands is probably the single best mental cue you can use.
