Claud,
My apologies for not getting back to you sooner on this...it was
evidently lost in cyberspace.
The Zero-Based RSI is simply:
RSI(periods)-50
There is far more to this than the vendors let on. It was originally
an article for TASC done by Tom Hartle in 1997. The following links
are for a PDF of the article and the TASC article indicators.

Hartle has been a big advocate of the RSI and more recently wrote an
article using a shortened version of the RSI...something like 3
periods. Notice that in his article he uses the standard 14 period
RSI while the vendors use a longer 30 period RSI.
I'm somewhat intriqued by the fibonacci reverence as this was also
something that Baeyans thought useful.
One final thought was the foreward reference used in the TASC Trader
Tips indicators for the expert. The forward reference means that you
would not be able to use the indicators until after the fact.
Hope this helps,
Preston
