Tom, let me illustrate the answer by the following question:  What is
the value of subscribing to ANY "real-time" data?

The answer, of course, is to get a close estimate of the current price -
what you could buy or sell for.  Although it does not give you a price
wich is CERTAIN for the latter purpose, it should give an
approximation.  How close that approximation is to the real thing
depends, at least in part, upon the accuracy, timeliness, and
completeness of the data.

How satisfied would you be, for example, if your "real-time" feed
provided only one S&P futures price every two minutes?  Well, DBC is not
quite that bad, but it seems that it is now delivering only about half
the price updates that actually are occurring.  And often, one of the
prices missed happens to be the high or low for the current intraday
bar.  This could have a significant impact upon an indicator or system.
