Results and quality are often not entirely linearly correlated.

MrBeast said something along the lines of, spending 2x longer on a YouTube video might lead to 10x more views. The reason for that is, that a video that does decently well and a video that really goes viral are often quite similar in quality, it's just that last bit of effort to take everything from good to perfect that can 10x or even 100x your results.

In that way, it might be better to upload 1 really good video every month than 4 great videos or even 30 okay videos.

I'd imagine the same goes for blogging.
