I did your homework for you since this is short & easy:
The only one "twizzle" Plushenko did, which is not a part of his required Step Sequence element can be found right here :

It lasted not even half of a second and his foot barely left the ground but I suppose it can qualify as a twizzle if we apply its definition very, very liberally.
The other twizzles can be found here :

Except all three are a part of his required Step Sequence element, which does not count as an in-between demonstration of one-foot skating. :sarcasm: Even then, you can see at 3m37s mark, he actually slipped on the last turn. http://www.youtube.com/watch?v=uZeQlQ_p4ZE#t=3m37s
As a result, based on the above review that your claim re: he did twizzles all over the place, is now firmly debunked as false. He barely completed a twizzle once outside of his required elements. In fact, one should say he had zero twizzles in his program outside of the required step sequence element.
If you had seen his all programs in the past, then you know he has one of the best twiizzles among the men.
