Hitreg and netcode still bad

I really payed attention to the hit reg. Played breakthrough Cairo attacking side. First take normal hit reg feels good some shots not counting by server. Movement is good. Seems normal. Bloom feels normal. 

We take A and B. 80 tickets we Move up hit reg still the same feels ok.  Movement feels off. delays in in sprint start/stop. Sometimes hitting the trigger has a delay. 

We take A 42 tickets left. Move up. Now it feels bad. Getting stick on random stuff out of view. 110 fov. Hit reg is bad. Server not counting roughly 20% of shots. Dying around corners even dying behind walls or cover. Movement is trash. Sprint sliding even interactions are bad. Insta dying when shot. Even was in a death loop.

We take A and B 58 tickets left. Move up. Now it's nothing but explosions .Movement is still bad even aiming feels off. Like random spikes in sensitivity. Changed controller new controller only 6 days old. Fixed nothing. Hit reg is bad dying fast dying in cover dying around corners. Takes almost a few mag to kill roughly 17 to 20 rounds. Shooting the enemy they can react. If the shoot me I can't react can't do nothing it's like you freeze for a  few milliseconds then just insta die.  

We lose. 

4 players on enemy team above lvl 300 and are 70/4 high unrealistic K/D with bad hit reg and netcode. I say cronus zen players. Our team top plays lvl is 94 and he has a 43/26 K/D our highest level was 120. My K/D was 31/12. 

Something is not right here. I have this strong feeling it's a match making thing.

Engagement Optimized Matchmaking (EOMM) is a system designed to maximize player retention by manipulating match fairness, often prioritizing a specific win/loss cadence over strictly balanced skill-based matchmaking (SBMM).

That sounds and feels like what is happening here. This bad hit reg is pat of it. Why would it be OK in the start of a match but get worse at the end.
