It's using the same or very similar methodology as these estimates:

Adjusted Even-Strength Plus-Minus

It's about as reliable of a "comprehensive" stat as there is, at least for even strength play. It's not perfect, and it's reliability decreases as the sample size of game decreases, but it gives a good idea of the general effectiveness of a player at even strength. There are other factors which can influence it and these would have to be considered more subjectively.
