Geomapping profiling

[OctavBotnar]

Geomapping profiling suggests JTR lived in the area where he committed the crimes - now i'm inclined to believe this and therefore this would rule out a good % of what i feel are way too many suspects in the first place.
However, i would be curious to hear what other's think-is the Geomapping profiling flawed on unreliable?

I'm not exactly an expert on that subject, but I think the one "flaw" it has (if it can be called thus) is that it's based on data, raised over a more or less limited period of time and a more or less limited number of cases. By analysing that data and adding elements of behavioral psychology, what we get is kind of an "average value" (for lack of a better word) which tells us that the AVERAGE murderer is very likely to commit their first crime in close vicinity of their home, as to secure swift and safe retreat. As time passes, they tend to operate farther and farther away from their home, but almost always still within a certain distance because if something goes wrong, it's very risky if the way back home is very long.

So, I think this tells us where Jack MIGHT have lived (if he had a permanent residence at all), but what exactly his first murder was is open to much speculation, so the information that the first murder might have been committed close to where he lived doesn't help much really
