What is the fastest time you can clear Alkaizer run with 4 chars?

I have read about single player clearing Alkaizer run in 5 to 10 minutes on MP0/1 using strafe build.

I have try using strafe build and the fastest time I can get is 32 minutes, most of the time either spend gathering 4 chars whenever I do a vault or one of the character got stuck and kill by the monster.:o

Monks/wizards blow through it if you are geared. (TR monks)
