If I remember right you've asked this same question several times
before, Gerald, and the answer is the same as it was before.
For YOUR trading style, the "adjusted" prices are apparently
suspect and useless. Fine -- don't use them. But you don't have
to keep claiming they're useless for ALL trading styles.

Continuous contracts are ideal for most/many systematic
approaches that are more interested in continuous (without jumps
introduced at contract roll) price waveforms than in the specific
price levels. My systems work by calculating values based on
recent price action. Everything is relative to the recent
action, so contract-roll jumps throw everything out of whack.
Absolute price level, however, is irrelevant. So adjusting the
price levels to remove the inter-contract jumps is very useful.
Just because you don't see the value doesn't mean it doesn't
exist. Many of us find continuous data invaluable.
