Whenever i read a paper, i do have troubles understanding the fine details. That one math formular which is nowhere explained? Yeah good... I often enough, get the idea and details like results but thats it. Those papers are not tutorials and they are not written / done to be reproduced and easy understandable. They are, in my opinion, written for other science people who spend there work time doing something similiar or need to solve the problem what the paper solves and rebuild those results in time consuming work. Probably still better than having no paper but still way more work than just using it. i do read "the morning paper" (https://blog.acolyer.org/ https://blog.acolyer.org/) and he is really good in reevaluating papers. I'm very curious how much time he spends reading and analysing them.
