about the tooltip info:
take a deagon fiend bow (well, tahts what i had in chest)
original_speed = 2.4
speed = 1.476 (with 38.5% mastery) ==> shot shows 1sec cd
speed = 1.107 (play lute on top) ==> shot shows 1sec cd
speed = 0.83 (use strong stimulant) ==> shot shows 0sec cd
[ edit ]
about the shot spam:
i use the addon u refering to, too. its callled ntCombatLogMod and has a precision of 0.1secs.
when i "spam" shot with my xbow of 4 speed (original one) i get cd on shot spam
when i use dragon fiend bow of 2.4 speed i can almost spam it
the difference is almost obvious that doesnt need to be recorded. idk if i spam every 1 sec or 1.5 (1.476secs precisely), but with xbow of speed 4 it shoots every 2.46 according to calculations.
tehre is a major difference in the numbers as u see (1.476 and 2.46) which should make it obvious even without any addon
i may go try test in some duel soon to see, but from my experience it is clear that with 2.4 speed u "spam" shot, while with 4 speed u fill skills in-between due to cd involved after firing
