Sequential VS Batch fire systems

All the applications that Robert J. Harris quoted in his original post  were
high-speed, high power applications, and sequential fuelling is  not going to
give you anything here.  What sequential injection does give is better low
speed, part load combustion stability leading to better real-world driveability.

Would anyone like to comment on batch fire vs sequential injection systems? 
What are the real world advantages to each under specific circumstances?  GM
went to sequential systems recently on the new camaros and corvettes, WHY?  Is
anything really gained with a sequential system in terms of performance,
efficiency or driveablility?
