Sorry for the double post, however I could no longer edit my last reply...
However let me post some interesting things from the SF:IV anime trailer that hints at Ryu's abilities which is why the Canon Guide for SF will be getting a revamp in the future, so I'll explain here...
Since we have been able to measure and calculate speeds and feats in comic books which don't animate, and people have calculated DBZ speed with animation, well people from srk.com have calculated the speeds at which Ryu was moving at SF:IV and yes...they are indeed impressive, because in the SF:IV anime trailer when Ryu fights Gouki.
He charges at Gouki with so much speed, that the sheer impact created a Sonic Boom. You cannot achieve this sonic boom affect unless you are absolutely traveling at high speeds, and the minimum speed that Ryu would have needed to travel in order to create the boom affect, would have been 761 mph. Meaning that Ryu was at least traveling at 1116 feet per second to reach Gouki.
It took 5 seconds for Ryu to reach Gouki, meaning he covered a distance of 5,580 feet away from Ryu, in order to create the Sonic Boom. The second time Ryu rushes at Gouki and lands the Shoryuken it took 2 seconds so it would equate to 2,232 feet that Ryu would have traveled to land the Shoryuken on Gouki.
So if you watch the trailer again, at 2:48 Ryu chargest at Gouki, and at 2:53, Ryu reaches Gouki causing a Sonic Boom. Again, one cannot make a Sonic Boom unless they themselves are traveling at insanely high speeds.
I had actually predicted that Ryu was capable of such speeds years ago, however due to there not having anything to back it up, it was denied. However with the release of SF:IV, and the anime trailer released by Capcom it gives you the showing that Ryu is capable of such speeds.
Ryu's reaction time is ridiculous as well, considering the estimation of how fast Gouki is throwing his projectiles here, from this link, read here from srk.com...

Gouki launched a barrage of 17 Air Fireballs at Ryu in 1 second, yet, Ryu was able to dodge and counter Gouki after this. Remember here, that these projectiles would be traveling at fire arm speed (Dee Jay is one of the Weak characters in SF and his projectile is 761 mph or 1116 feet per second).
This is a showing that Ryu's speed, and reaction are well beyond human lvls, and surpasses many super human comic book characters as well.
Now, remember this, that Ken would need to be near this level to even remotely compete with Ryu, in which he has actually done so in the past. Sagat without a doubt would be in no less then equal to Ryu in similar feats.
Deejay being weaker then Chunli and having a projectile that travels at 761 mph would mean that Chunli's speed would also need to be vastly impressive in order for her to be one the strong SF characters.
So again, Chunli is being underrated, and the feats of the SF cast are more impressive then previously assumed Pre-SFIV. Ryu is far more powerful then we had originally thought, and SF:IV is proving the case in his part.
However, I will simply conclude a draw, since Team Ninja also has impressive feats.
