Depends.  They are (on average) 13 ply deep computer analysis.  This is better
than the average player will manage, and the data should be very consistent.
However, if standard human analysis for opening positions exists, it is almost
sure to be better.  For openings, humans have been debugging them for hundreds
of years and carefully exhausted many false steps.

The potential uses of the data are unlimited.  Or, rather, they are limited only
by the imagination of the one using the data.  You might minimax it.  You might
search for novelties.  You might iteratively improve it.  Who knows?
