nice skiing, you will be able to nail 28 with some small tweaks. Couple things to think about when you get up and stand on your ski; work on how you stand on the ski outside the course - 1/2 the time you are skiing, you aren't in the course, this is a good time to practice how you stand; before the pull out, during the glide and when you exit the gates at the end of the pass - this will build muscle memory:
a lot of this has been mentioned already but:
-stand tall with most of your weight on your front foot
-arms straight - they are an extension of the rope
-squeeze your butt cheeks to drive your hips forward over your front foot
Since we ride the ski with 1 foot behind the other, it is natural for 1 hip to be behind the other, which means your weight is back naturally - to counter this align your hips perpendicular to the ski, meaning, bring your back leg (hip) forward to align with your front hip like a T - this was huge for me to get into shortline and get a better stack, with weight up over the front foot, especially on the offside.

Also, the pull zone shortens but the intensity increases as the line gets shorter. This is very apparent at 22 vs 28 IMO. It appears you are loading a little early, which is causing the boat to throttle you out of position at the 2nd wake. Try to let the ski finish the turn a little bit more and delay your pull a fraction while maintaining your stack through the finish of the turn. This should set you up for a smoother wake crossing and transition to the next buoy. hope this helps.
