bolt torque
I think as long as you are using a straight extension there is no difference. I think the torque equation only comes in to play when using a wobbler, u-joint socket, crowfoot......etc.

I wouldn't think they would be very accurate since the torque loss using an extension with an air impact would depend heavily on the physical properties of the extension material. There are calibrated torque limiting "extensions" used with air impacts used in tire service shops.
There would be no torque "loss" using an extension with a torque wrench unless the wrench is not "straight on" with the bolt or nut.
There are formulas for use with a crows foot type wrench.

PM me with a fax number, if possible. I have a manual from a torque wrench mfg. that shows all of the different ways to calculate the torque. A lot more than I can type here. The basic equation is as follows:
Ta = Torque exerted at the end of the adapter
Tw= Torque wrench scale reading
L = Lever length of torque wrench
A = Length of adapter
Ta = Tw x ( L + A )
------------------

I don't know if this is what you wanted but I hope it helps.
