I woke up at 3:00am thinking "but I didn't explain Pareto".
Then I went back to sleep.

The Pareto Principal is that 80% of the task takes 20% of the effort, the last
20% of the task takes another 80% of effort.

We Econometricians (Statistical Economists) use it to justify putting in little
effort on tasks. (Ask me to graph the next 10 years interest rates & I'll give
you a +or- 10% graph in 5 minutes, ask me to get it +or- 2% & get ready to
wait).

eg: writing a good chess program: Maybe after 100 hours planning & programming
you have a working reasonable program.  It takes a further 400 hours to get rid
of bugs, perfect the gui, get it just right.


eg: You look at a chess position.  In 1 minute, in your mind, you know the best
three moves & their likely reply, in 10 minutes the worth of your concentration
has come up with only marginally better analysis.

eg: Rebel knowledge, the first 100 is Rebel default contaning ALL the really
important stuff, go to 200 pick up some worthwhile extra evaluation, go to 300
helps a little bit...... going from 400 to 500 may (& I'm not Ed, & I'm
certainly not denigrating/insulting Ed) introduce very little extra "knowledge".
