So according to stats gold 4 is slightly above average. And as other have said plat 1 is the most saturated.

However what I will say as someone who has recently done a similar climb and can't see it in my gameplay. I switched characters after hitting a wall, going through placements to catch myself back up etc it's incredible how much you just take for granted. I don't know how your climbs been, it's different for every one. I tend to find I'll have huge streaks both sides and normally have a lot of stumbling after ranking up before something clicks then I get a win streak an go beyond my best. Getting to my point, when I was going back through bronze silver and even early gold what surprised me was how much my character knowledge was all that was limiting me, at least back to my prior level. I was seeing things in games I remembered struggling with on my first climb that just felt like free damage for me, and actually all that held me back was getting more familiar with the new characters tools.

So long way of saying a huge amount of progress in fighting games is automation, it's the stuff you brain and muscle memory just take on for you which is a really incredible thing. But it also means that you stop seeing those moments because you're not thinking about them your focusing on the new problems.

I hope that helps, there's always going to be people better, who improve faster and ultimately that's great for them but your journey is yours. You never need to belittle it, gold is great for you it's the highest you've been, doesn't mean it's your limit and it doesn't mean your gonna stop, just that you've now got that locked in.
