Left side Bend on Backswing Timing

Hi Tyler
I saw the video on right side bend timing and it was very interesting including the counterintuitive reveal that the right side bend increases at or after impact
Do you have any thoughts,data or empirical observations on the timing of left side bend? This may include the torso and/or the pelvis
I know you have a video on early left side bend.
When I try to do this I tend to tilt my head left(right handed golfer) and maybe lift in transition. I also find when I try to left side bend the pelvis early I don’t load the right glute well and find I feel I load the right glute better if I keep the left pelvis higher for the first half of the backswing. I realize there is some subjectivity to these statements as I don’t have access to 3D.
Is there any benefit or data to support different timings of left side bend i.e. later of either the torso or pelvis?

Thanks,

Thanks Tyler
Is there any info on the timing or extent of the pelvis left side bend?
I have read some info recently that it may be better to delay the left pelvic sidebend till closer to transition. This “feels” better to me and seems to load the right glute better.
