It depends on your definition of "properly," since SMW coincidentally also has a massive shortcut (the Star Road) that lets you beat the game very quickly without bending the Matrix. A TAS of such a playthrough is only 10 minutes.

There's also a TAS of 100% completion playthrough of SMW's 96 exits, which takes considerably longer. (about 1.5 hours)

There's a TAS style for every person. :)
