humm R u sure U r talking about SX2!? I mean SX 2 has the PDC, Plugin Delay Compensation, so that ain't so much a prob. anymore....
But taking yer tip I will suggest that People use the delay on each track (Even if ievery track is properly compensated and it sounds on time) as this can most of times give u a very cool shuffly or tighter feel... typical values between -5...5 ....
