Really? Sure sounded like you were saying "strength > martial arts" to me, but I guess my logicsmithing isn't so good.
Here's anecdotal evidence. I know it's a fallacy, but bear with me for a second:
The guy who's teaching me kempo is a pretty small guy. 5'4" 140 lbs, maybe? I'm 5'10" 200 lbs. One of the very first things he showed me was how a small person can overcome someone who's larger and stronger than they are. A lot of kempo involves utilizing momentum: like if someone steps toward you, your punches are set up to channel
their momentum into the blow. If someone steps into a punch, you clothesline them by the neck.
Another big part of kempo are grapples and throws borrowed from Jiujitsu. He had me put him in a sleeper hold. The next thing I know, this little guy tosses me like a ragdoll.
Martial arts skills shouldn't be discounted. You also shouldn't discount people who are smaller or weaker. It is foolish, whether you'd like to believe it or not. Someone who's smaller than you are can still be a serious threat.
I didn't ignore it. This topic was brought up above but I hadn't had a chance to look it up until now.
That said, I discovered this chart:

As a result, I respectfully withdraw my comment about average running speeds of men and women.
