I just equalled the WR in You Have to Win the Game (4:56). I'm not actually 100% certain that is the fastest run - I still feel like there's a 4:52 out there somewhere, but it feels good. The run is, however, definitely improvable. If I can get another second or two off I might upload it to YT, and/or Submit to SDA.

How come it says that the fastest time is 5:17?
People don't always submit (new) records to SDA, especially when:
1) The quality is low (SDA hosts almost exclusively high quality videos)
2) A new route has been found, often leading to multiple new WRs within a short time
3) They forget
4) They do submit, but the new record gets stuck in the SDA pipes.
In this case it's a mixture of 1+2 - I discovered a trick which cuts off around 10-14 seconds, someone else discovered one that cuts off about the same. Now you might notice the WR is only around ~21 seconds faster than the SDA run, but I just said ~28 seconds could be cut off. That should give you an idea of the quality/level of refinement on the WR run - the run might be faster, but it looks a bit sloppier. Part of that is because of new, difficult tricks, but also, it means people are still beating the WR a little more frequently.
The best way to find out the WR is to look on the twitch pages of the best runners. In this case Ibldedibble (the current SDA record holder) says he has a 4:56, which is what I now have. But even those aren't necessarily up to date.
