I have read the Skill Points thread and I am impressed with the depth of your analysis and rationale of your conclusions. However, I do believe you based your equations on certain assumptions that may be throwing your conclusions off. Of course, I may be misunderstanding one or more of your points, so take that statement with a grain of salt.
In any case, my future line of experiments will not focus on the acquisition of Skill Points at all. I wish to study the interesting phenomenon I witnessed when I actually paid close attention to the center of the map and the subtle changes it made throughout my game.
