Dunno if you already made something with regards to this, but if not, here is some implementation for the t7 4p bonus:
Changes are to v3.1a
Added value to 'Advanced infos'!E5:
=IF(Gear_Buffs!B88;E6*(0.3+0.03*daegis);0)*10/lifetap_freq*IF(glyph_lifetap;1.2;1)
Added value to 'Advanced infos'!E6:
=300*(1+Gear_Buffs!B127*0.02)
Forgive me if there is something I have forgotten, but should accomodate for kings, glyph of LT, Daemonic Aegis and your LT freq.
Now, to ensure this is added to your stats, I've appended the following to Gear_buffs!G83:
+IF('Advanced infos'!B6;'Advanced infos'!D6;0)
Feel free to make these modifications yourselves if you can't wait for the next version. Hope it is of use to you.
Oh, and as an aside, personally for me (avg itemlevel of around 217, affli lock), the 4p bonus, with glyph of LT, adds up to 59.4 SP, making 4-piece a clear choice over almost any other gear combo for me personally.
Important note: Doesn't work if you set LT freq to below 10 (but neither does glyph of lifetap if you set freq to below 20). But too late to make the changes, as it's 3 am here. User beware
