Being a CAT5er myself, I feel like I've witnessed quite a few different attack styles already:

1) Time Trial. He slowly solos off the front at 20-30 watts higher higher than the field. Next thing you know, it's the last lap and he has a 45 second gap.

2) Strong jump. A 5-second long attack that is almost immediately shut down by the field.

3) Strong VO2 system. Attacks strong for 30 seconds, then runs out of steam. Gets caught by the field. Repeat x 10.

4) Good cornering skill. He goes to the front right before the super technical section of a criterium, and coasts through the turns faster than the field. A natural gap forms behind him.

5) Good all-out sprint. Sitting in the top ten for most of the race, then busts out a monster sprint at the last corner, developing a massive gap on the field.

As I cat up, I have a feeling instances #4 will become more scarce, as everyone's cornering skill will be pretty solid. Is that a good assumption?
