From the source:, analysis.c
const char *aszRating [ RAT_UNDEFINED + 1 ] = {
N_("Awful!"),
N_("Beginner"),
N_("Casual player"),
N_("Intermediate"),
N_("Advanced"),
N_("Expert"),
N_("World class"),
N_("Supernatural"),
N_("N/A") };
static const float arThrsRating [ RAT_SUPERNATURAL + 1 ] = {
1e38f, 0.035f, 0.026f, 0.018f, 0.012f, 0.008f, 0.005f, 0.002f };
