I don't have my manual on me but if thats the question where it asks for DeltadeltaT value (Tf-Ti) and then the absolute value of that, you use the formula

sqrt((deltaTi)^2+(deltaTf)^2) i believe...so its sqrt ((.5)^2 + (.5)^2) and i think i remember getting something like .7071 so that is probably the same value for everyone.
