I digged a bit and couldn't find the post I wanted, but as far as I remember the average potency are the following :
H IDC P TTT H TTT P IDC H TTT P TTT => 135.7
HP IDC TTT => 133.X
You shouldn't go for HP IDC TTT HP TTT TTT as it's a little less efficient than HP IDC TTT rinse and repeat. The only time you will apply HP IDC TTT HP TTT TTT is on your very first opening as your CT is buffed by BfB and IR and better to keep the fully buffed DoT run.

Concerning the BiS list, every calculation tends to give the following as 463 (465 in fact) :
- Wyrm's Armet
- Wyrm's mail
- Allagan Gauntlets of maiming (T2)
- Hero's belt of maiming
- Allagan trousers of maiming (T1)
- Allagan Sollerets of maiming (T5)
- Allagan choker of striking (T2)
- Earthquake's Earrings
- Hero's Braclet of Slaying
- Allagan ring of striking (T4)
- Allagan ring of maiming (T4)

I don't know if it's because I'm running it under Excel 2007 and not 2010 but the solver is acting very weird. I have to run it multiple times as it doesn't always find the same result. Do you have the same behavior Dervy?

Anyway we won't have a real BiS list as long as we can't confirm the Acc's cap for T5.
