Does prodeo extended book learning actually work?

[ozziejoe]

sigh. I've just spent two hours trying to see if the extended book learning feature works. and i still can't tell if it is.

I have turned off every learning feature but extended book learning. see.

http://www.top-5000.nl/authors/rebel/hints.htm

I can confirm that htis parameter is turned on (using the parameter.txt), but i see no evidence of the extended learning function. Does anybody know what data file the learning data is suppose to be stored in? I could be looking at the wrong file.

I insert the parameter text file below, in hopes that it will shed some light on things

[Engine Master = off] * off
[Engine Learner = off] * off|on
[Book Learner = off] * off|passive|moderate|strong|aggressive
[Position Learner = off] * off|on
[Extended Book Learner = read&write] * off|read|write|read&write
*

I think that you need to have Book Learner = on (passive|moderate|strong|aggressive) for Extended Book Learner to work.

Anyway, Ed ditched all these learning functions in ProDeo 1.5 (and beyond) because he considered them obsolete against EOC Learner = on.
