I mentioned that I've counted mine, but the only public-accessible way to tell is by counting them by yourself, perhaps screenshot each of your games in the ELITE app. There are other stats that you cannot physically see as a member of the public, however I've forgotten an example. I will update this comment when I remember.
Thank you a lot. I did send an earlier version of this to NGTZombies, but they either ignored it or never saw it. Then I sent it to MrRoflWaffles who replied and said he'd verify it one day should he have time. But after hearing an NGTZombies video where SpiderBite mentioned he doesn't think it's kills to downs, I felt I had to post this to avoid being cheated. I'm not a trusting person due to the large amount of people who take ideas and say they're their own.
not saying that your theory is wrong but i have shotguns and a few of my friends list do aswell.
K/D i have found out is the majority of how to get shotguns.
the only difference is that i found out was that if you have good K/D but low on revives headshot gibs and others you really need high K/D.
example my friend got his shotguns 207 k/d
i got mine @ 167
my other friend got his @ 175 K/D
I checked out that i had top of every leaderboard (my own friends leaderboards) except for kills when in got mine when the other two had top kills but a few stats lower on the rest like middle of my leaderboards.
Also i have lost the shotguns over 40 times now which meant i was hovering on my minimal K/D
so i played and targeted 1000 kills with 1 or 2 downs.
I am now 195 KD i can go get perma jugg without losing shotguns which was the majority of why i lost them.
so from my experience it mostly on K/D but the rest of the stats matter heaps.
now i can have games of 400 kills 8 downs and not loose them.
