Current formula for working out Power Word: Shield (Patch 3.2)

(base_absorb+(0.8068+0.08*BT)*sp)*(1+0.05*IMP)*(1+ 0.02*FP)*(1+0.01*TD)

* base_absorb is the base absorb given the PW:S which is 2230 at the moment

* BT is your Borrowed Time level

* SP is your Spell Power

* IMP is your Improved Power Word: Shield level

* FP is your Focused Power level

* TD is your Twin Disciplines level

e.g. Tried this on my priest with those above talents with 1945 SP (2230+(0.8068+0.08*5)*1945)*(1+0.05*3)*(1+ 0.02*2)*(1+0.01*5) = 5752

How it DOES work: Power Word : Shield is absorbing 4670 damage here.
