Video #1 - First thing I see on your approach is great vision-up. Your Pacing is a bit monotone with no real ramp-up noticeable yet, and there is a pause between 7-8 and 9-10, which is not uncommon - but we want to get rid of that "skip-step" as I call it. LOVE that big arm load as you push out of 9 into 10! And un-lean to a BIG vertical, ABOVE release at 10 - SUPER takeoff control here! Use the cursor arrow keys to go back and forth between the last frame of video with your toe still on the ground, and the next frame with your toe off the ground - see how you're pretty much Above and hips are driving shoulders UP and not rotating your back down toawards the bar? Really Excellent. Video #2 - Better initial pace and energy 1-6 in this approach. Flaw here is that step 7 goes out and you push off, like a basketball cut, instead of bringing it across your 1-6 line to start the turn. As a result 7-8-9-10 are all reaching a bit, which slows pacing and steals energy. Another good release & Above at takeoff, but a bit further away from the crossbar, with a bit less energy at 10. Not so much skip=-step on this one either... Video #3 - Ugh - this one the pacing is just so blah all the way in. No energy at 10 = no chance to make the jump. Simple as that. Video #4 - OK - better energy here (Thank you). The skip step is just very slight - not a bad approach energy-wise. But go frame-by frame and look where step 6 is - THOUGH the 45 line. From here you bring 7 across nicely (no step out & push off). Ultimately it has you closer to the bar at 10, not leaning into 10, and so the release is through vertical. Advance the video frame-byframe and look at the frame where your head & hand are just on the left edge of the closer upright. Here you will see that you are WAY above the bar, but the apex of your jump is also WAY BEHIND the crossbar - not centered above it. Despite haveing a foot of clearance height-wise, your feet drag the bar off because of the series of events that started back with step 6 being through the 45...
