gchapell, did that work well--that is, did Polaroid respond to light the same as the film you used? If you still use a Hasselblad, you could test with digital, then switch to film back (if the sensor and the film consistently respond the same way)...
I myself did not use the back but it was used to check out lighting setups. As above mentioned, users would calibrate their eye to what they saw in the polaroid to their results in the film much like we do today translating what we see on the screen to what we see in the final print. Just as today with calibration tools and profiles we can achieve a tighter screen to print result.
