Match making broken

The normal progression last 5 seasons before this one, is when doing public BR, I get fights vs something like bots the first 5 matches, and my kd is 9 or so, then I am ranked up way above my level, and am annihilated the next 50 matches until my kd is around 1, and then I stay at that level the rest of the seaoson. Definitely not optimalt experience, but way better than this season, where I got the same start, bots the first 5 games, kd around 7+ but then annihilation the next 100+ matches. I am now at 0.5 kd and still get annihilated, all the while the last 100 matches where i been annihilated instantly i apparently am at the 99th percentile of skill distribution, which seems to be a way to mock me only, because it has nothing to do with reality.
