Need some help sorting out the timing and rubato of this section

[bustthewave]

Alright, so I'm trying to get a handle on rubato in general and it just so happens this piece I'm working on has an entire rubato section.

I've spent a bit of time on youtube and feel like I can definitely hear the difference between playing something rubato and not, and feel like I'm getting a handle on playing 'around' a rhythm without losing that rhythm.

I've attached the section I'm working on (hopefully it shows up). After finding some instructional videos and such, I'm wondering how to approach these triplets? Do I have it right to say that playing this section rubato would mean that each set of triplets in the left hand would sway ahead, and sometimes behind the beat? Would that sway back and forth (fast vs slow) generally alternate between each triplet or is that an interpretational thing?

Not sure if this is something that can be explained without someone being in the same room with me, but figured I'd give it a shot.

Thanks in advance!

EDIT: Not sure why I didn't do this before posting, but just did a search in the forum on rubato, and learned far more than expected. Thinking about rubato in terms of a free flowing artistic expression that gets muddied with words actually makes it make a lot more sense to me. I hear and experience music as much visually as I do aurally. The visual movies that play out in my mind don't always match the perfect tempo of the metronome, but they match the feel (such as a rising melody, I may play a movie in my head of someone grasping for their next hold while rock climbing, each grasp matching up with a note, and each grasp more desperate than the last, with greater gravity pulling on them the higher they go... I dunno, its something that my brain put together in a recent quietly intense piece I was working on). I'm thinking I already do this rubato stuff somewhat already without realizing it.
