If you look on that list, TC, you'll see that the first Base 100 Speed Pokemon is 69th on that list (including all 4 formes of Deoxys), so that kinda shows why Base 100 isn't considered super-fast anymore.
chao master Team Aqua Blue for the 3DS! Which side are you on?
100 can be considered decent. Not too fast, not too slow. This gen pretty much sealed the deal of 100 being declassified as fast by adding the musketeers and genies. Smogon letting the Latis and Garchomp open to the new metagame helped as well.
