Mob & NPC kill -server inquiry

So Maybe I’m not great at internet sleuthing to find the answer, or maybe there isn’t one. I would like to know if there is a script to find kill count of a particular mob through life of toon (not an addon like killCount) in this case “Death Adder”. I’ve been going after “Death Adder Hatchling” pet off and on for a few years, on multiple characters. To get it you have to Clear the Death Adders in a loop (or half) and pray an Imperial Python spawns in its place. Kill it loot it and hope you get a infant Death Adder. Like I said 3-4 toons for several years, about 50 hours twice a year, a normal grind. Except last week… wifey joined me in group.
After 50 minutes of looting she had 2… me, 0. Group kill, looting same. I returned to the grind thinking the drops increased. 30 hours this week AM & Late nights before/ after work.
Nada.
I think I’ve killed close to 2,000 Death adders getting 275 or Imperial Pythons to spawn… but in the time my wifey was running we killed 80 Death Adders with 16 Imperial Pythons and she looted 2 Death Adder Hatchlings…(she’d never gone after it before on any toon!) Needless to say she felt I was embellishing my estimated figures, never know so that’s why I need it. Because if she did get drop rates as such… well.
