Does anyone else deal with getting "stuck" at certain Grades every Season?

So, I've noticed something I seem to deal with consistently every new Season in DbD: I get to a certain Grade, with some ups and downs, but generally consistent upward progress, and then suddenly I stall out completely and can't seem to make any further Grade progress.

It's as if the game suddenly decides, "No, this is as far as you go," and makes sure to match me against opponents that I can't pip against. Or, even if I do pip/double pip, the next game(s) will see me matched against (a) Seal Team Six squad(s) that completely obliterate(s) me, until I'm depipped back down to zero pips again. It usually occurs around high Gold/low Iri Grades, and it's often a struggle to push past and get to Iri 1 for the Season, if I can even push past at all.

Admittedly, this experience is primarily on Killer side, as I'm a permanent solo queue sufferer who struggles to loop for the life of me, and usually gets stuck in Solo Queue Hell where I just get stuck in low MMR forever where my teammates refuse to do gens or sewer-slide on hook on first down, or I get found first and abandoned to second state on first hook, and then never healed, so I don't pay much attention to my Grade progress on Survivor side, since it doesn't feel that much under my control.

So, does anyone else feel like they experience this frustrating phenomenon?
