Are you cycling the safety between shots, when you move back to a low position? Make sure you are.
Get a single reload technique down and use it consistently, no matter what speed you're going. Don't do lazy reloads with sloppy technique when you're not timing or in the middle of a drill - go slow, sure, but the key is training muscle memory and not deviating from a set of motions. Toss the empty mag or forget about it, don't kick at it once it's on the ground. Magazines are the biggest wear item for a firearm, and doing anything more than bench shooting will wear mags and necessitate non-working mags get tossed out or rebuilt.
Add in multiple shots on the strings. Getting the first shot on target is vital, but you want to train your trigger discipline to break the 2nd and 3rd shot fast and accurate. Don't rush the sights, but don't shoot smaller than your target. You started doing this at ~8:20 but using the 15-22 should help with the timing and trigger manipulation.
Is someone giving you the cues, or are you alone? Calling out the cue yourself is good to start, but I would add in a shot timer or something similar when alone. You can get one for a smartphone for free that will give you a random beep cue and you can set a second one to cue a time stop to gauge how consistent your reaction time is.
What kind of target are you using? I really like the ranged silhouette targets that give you varying sized targets. It helps you get a better feel for going faster on larger targets and forcing a fast sight picture and good trigger control on the small targets. Much better than just shooting a paper plate or 12" bullseye target. Edit- saw at the end you're using a full-size silhouette.
When shooting with a friend using the color/shape/number FBI style target is really useful to add a small amount of thinking to the shot. Call out a color and double-tap all of those. Call out a non-primary color and shoot the two primaries that mix for it. Call out a larger number and shoot 2 that add/multiply to it. Call out a shape and a direction and shoot the shape(s) in that direction from the callout. Etc.
Shooting with a buddy who wants to do the same stuff will help a lot.
Take a training course! Getting instruction will help identify faults in technique a lot better, will give you more drills to practice, and you won't be practicing as many bad habits that get more ingrained the longer you go without outside instruction.
