Wow, great targets 3 and 4 for DK. But you're running too long after target 5, which is why it's slow... I think that could much closer to 10 seconds or even under 10 seconds if you didn't run.

You can jump much sooner.
For Kirby, after you do up-b, move your control stick to the right, so your sword thing can hit the target, instead of the wave, it's a lot faster.

But I don't use that strategy. xD
For Peach, you already know this, but you didn't run right away...

and instead of insta-floating to get target 3, short hop, uair, and fair target 4.
For Bowser, I just turn, full jump and immediately press b, and then angle the fire upwards. It almost always hits the target.
R.O.B.... variations of the counterclockwise strat really aren't really that hard when you get used to it... but it took me forever to do that. >_< you can get 7.xx easily with one.
Um, I watched all of them and those were the mistakes I think could be most easily fixed. I hope I helped somewhat.
