No offense, but you clearly don't understand much about what I posted...
Regression deals with a trend and determines whether or not there's a correlation between an x-value and a y-value, therefore, it's not a theory. Second, the line doesn't explain 100% of the data points, it can merely explain a majority of the data points based on the trend. Third, the trend holds true within a given range (from 7 messages to 234 messages) and may not hold outside the bounds of this range, which is where you sit.
Even if it did, then all it's saying is that the trend doesn't explain why you suck. The functions are merely a predictor of what one could expect in a majority of outcomes and by no means says that it's the law. If it was the law, then there would be a perfect linear or logarithmic fit, which we don't have.
The long and short of this is that I'm going to issue you a challenge to read a thread in it's entirety and not just the post above yours and a few select others. Hope this helps explain things, though.
