(1) Do you have a way to screen stocks with certain IBD ratings that's easier and less time-consuming than scanning the thousands of listings in their paper? (3 of your 8 screens key off of IBD ratings.)
I sent MM an email about this and he replied that it doesn't take that long to scan for these three screens. He's right. I've only done it a cople of times and it only takes about an hour. Last time I did it those 3 screens brought in 45 potentials.

(2) For the benefit of me and others who don't know trigonometry, calculus, or which ever form of math applies, could you explain how one calculates an "r-squared correlation coefficient"? I'm assuming the "r" is radius (which raises the question, Radius of what arc or circle?)--after that, I'm lost.
You are performing a linear regression of closing price relative to the date. More simply put you are looking at a chart of the previous years daily closing price and drawing a straight line through it. The R2 value is a measure of how far each data point is from that line. An R2 value of 1 would mean that all of the data points are exactly on the line. An R2 near 0 would mean the data is essentially random an the line is meaningless.

Hope that helps
