The games were not selected according to player strength, so you get whatever IGS (the source) had to offer. The selection criteria were 9x9, no handicap, and recorded territory. To select only games between good players you'd need a larger pool of games, which means going to 19x19 and "bootstrapping" final territory, e.g. via gnugo as suggested here. I am attaching a histogram of player strength for the games in question, translating IGS ratings as NR = 0, 31k = 1, 30k = 2, ... 1k = 31, 1d = 32, ... 9d = 40, 1p = 41, ... 9p = 49. Predictably, you have a large number of NRs and 30ks, a fair number of ~12ks, and some better players. I'd consider these ranks a lower bound on actual player strength, since IGS regulars are bound to create an unranked/low-ranked login on the side for things such as playing a 9x9, in order to avoid messing up their main rating.
