This is something I have always struggled with - missing the dumb stuff I should be hitting 100% of the time no sweat - and I've found that it's because my cursor and keyboard hands get out of sync. This wasn't something I really noticed until I realized a lot of patterns seemed easier with DT than no-mod.
More accurately, my keyboard hand moves more-or-less on time, but my cursor hand is too impatient. When I watched my replays at 0.5x, I saw that a lot of the time, my cursor would move over a note, then move off it before I actually hit it. Even on notes I did hit, a lot of them I was practically hitting on the way to the next note, way after I snapped to it.
This is worse on lower AR because I'm paying more attention to notes that are just appearing than to the notes I'm currently hitting. And it gets worse the more I retry a map, since I remember where notes are and thus pay less attention to reading them (I'm thinking about future notes as opposed to the notes I need to hitting right now). And like you, I also tend to have more problems with it on faster maps and bigger jumps because I feel pressured to move faster.
This is still something I'm working to overcome, but what has helped for me is to relax. You have a lot more time to get to the next note than you might think. Pay more attention to the note you're on, and don't move on to the next note until you know you've hit it. It's hard to do at first, especially since your conscious mind is intruding on your muscle memory, and you might have problems hitting hard stuff you could do before because you're intentionally giving yourself less time to react...but I've found it's helped me hit the "easy stuff" a lot more consistently.
So while it's noticeable pulled back my upper limit, it's brought up my lower limit, which I think is more important. Master the basics so when you move "hard stuff" into the "easy stuff" category, you can actually see it in your performance. At least, that's how I see it.
