Perplexing - Stats are off?

Take a look at these captures I took off Waypoint today. These are conflicting reports. What gives?

I’ve noticed stuff like that too. My wins being off, even game stats. Like it still says I’ve only gotten one assassination, when in fact I have a ton.

Stats in this game don’t seem to track properly and I have no idea why. In fact I’ve had stats roll-back during a game

Yesterday I had a match where I got 7 kills, a couple minutes after my 7th we underwent a host migration and I was knocked back to 4 kills on the scoreboard. Never seen a host migration do that before.

The challenge could possibly count top 4 in flood or top 2 in regicide as wins. I know to get a win on record you have to be 1st place, however it may not apply to the challenge. I doubt this is it, but it’s my best guess as of now.

I noticed things where I went to look at my assist medals and it said I only had 4 or 5 hundred, but my commendation has over 1000 (Assistant - Master). The commendation counts any assist medal you get (Hill assist, distraction, etc) towards it, but the medals are just regular assists.

It could be the same kind of thing. One counts more specific than the other.

How much time passed between each picture was taken?
