Good observations. General downward trending: That's been the case with us. If I went back and corrected the first few weeks of points, I would probably assign more points to the individual tasks, moving up the first few weeks of values. Yet I tend to correct the number of points assigned to each item before I mark it as "finished", thus somewhat normalizing the value of each point. Large spike in point values: Nah, what actually happened is that we filed many more small (1-point) bugs, rather than overestimating values of new bugs and features. Thus, after showing off the new versions and handing out alphas, we'd have more work items at smaller valuations.
