Personal Force Fields Explained, Please I'm having trouble understanding personal force fields armor upgrade. 
Specifically the charges vs hp, example the purple force field.  10 capacity, 5 temp hp, fast healing 2.
Here is what I'm not sure if its 10 charges of 5 hp / or if the 5 hp comes out of the 10 capacity. Also does the fast healing recharge, recharge the capacitor or directly into the hp.
