IIRC the discussion at the time was about whether gnc should or could be 
used for trading.  the result was "no" and it was decided that the price 
db should only have one entry per day (some people wanted multiple 
entries per day in an attempt to use gnc for trading, that was never 
going to work as gnc is a crap model for all the other stuff short term 
traders need, like quick graphs, moving averages, etc).

given that, are you unhappy with the way gnc records date / price 
combinations ?
