I would love to hear about those two stunts and how they are executed badly by many a flier. I know mine are grotesque.....I love that word...and at this point in my flying just trying to get through them as well as I can with what skill I may process.
I'm not Ted, but:
Hourglass: the first turn wasn't too bad. It was hard to tell whether you were on a vertical line (you were probably in front, because everyone in Advanced is), but your third turn was big (probably because of loose lines) and not only did you take it too far, but your downward line wasn't straight -- you leveled out a bit. That forced your last turn to be early, big, and generally ugly.
Take a plumb bob out to the field, and hold it right over your eyes to get an idea of what vertical is. You'll probably be surprised at just how far back it is. That's where you want to put the center of the top line of the hourglass, and the intersection points of your overhead eights. If you move off of that at all, you should be moving it further back, not forward (forward is easier for the judges to see, and easier for the wind to smack you around).
Clover: Play the video over and over again. If you have a tool that'll let you play it frame by frame then do so, marking the airplane position with a dot on the screen at each frame. What you should see is four loops (well, 3/4 loops) that are all the same size, and that are nestled into a cross. What you will see is four loops of four different sizes, with the intersections splattered all over the place.
I tried for years to pick out an intersection (i.e., some feature in the background) and fly to it. I always ended up overshooting on my first loop, then hitting the intersection on the third -- which meant that I came up through the center of my first loop, instead of kissing it's left edge. For the last six months or so I've been still trying to hit a predetermined intersection, but as soon as I do that first loop I throw away whatever I had and just run with what I establish with the first loop. It has helped me to consciously fly the first level segment (after the first loop) so that it's long enough (it should be close to 45 degrees). For me, at the moment, the hardest part of the clover is starting the second loop at the right time.
