"diff" is indeed the raw difficulty of the wave, taking into account the number, average energy, intelligence, and general nastiness of each type of enemy, as well as some fudges for super-dense or super-sparse universes. It is supposed to reflect the normative amount of time necessary to clean things up. Think of par in golf. It is not divided by time to get the efficiency rating, however. The following does the calculation: effectscore = ((double)curscore / possiblescore) * atan2(power, (double) timer - 9999.0) / pi_over_2; where effectscore => efficiency rating power => "diff" timer => number of time units taken + 10000 curscore => how many points you got this round possiblescore => how many points you coulda got The atan2 divided by pi over 2 is very nice in that it yields .5 for two equal arguments, and asymptotically approaches 1 for large power:timer ratios, and 0 for small power:timer ratios, and is symmetrical to boot.
