Does race affect movement speed?

I'm finding conflicting sources.

Race does affect movement speed

1. From uesp:

   The movement speed of each race is dependent on its height (...)

2. This video showing a test.

3. Some guy on the bethesda forums did a test:

   Wood Elf (scale = 0.98) : 47.3 seconds to run the track.

   Imperial (scale = 1.00) : 46.35 seconds to run the track.

   Nord (scale = 1.03) : 45 seconds to run the track.

   High Elf (scale = 1.08) : 42.9 seconds to run the track.

Race does NOT affect movement speed

4. From elderscrolls.wikia:

   Without console command modification, the damage output, damage resistance, jump height, run speed, weapon reach, etc., for all races remains at a scale of 1.00, with the race specific scales being purely cosmetic only (...)

I was only able to find tests showing that race does affect movement speed, so is this the correct answer?

UESP is usually correct, and it has proof, so I see no reason to doubt it.
