WebYou want to know how many kills are you away from 1.66 KD. (1.66 x 9,028) - 14,943 = 43.48. Basically, if in your next game you score 44 kills/0 deaths, you will reach your target 1.66 KD. Of course, if you die once or more in that game, you will fall short and will have to recalculate to see what you need in the next game. Hope this helps. WebThe pA2 is defined as the negative common logarithm of B which produces a dose-ratio of 2; hence, pA2 = -log B = -log KB = 10g(1jKB). Since IjKB is the affinity constant, the pA2 may be viewed as a measure of affinity. In these calculations the units are molar. No antagonist A A' (Log scale) Agonist concentration
