I’m not too sure what you mean exactly. I basically read some form of Japanese, like manga, books, newspaper articles, signs, games etc on a nearly daily basis. I was able to pass N2 after three months of Bunpro where previously other grammar resources like Kanzen Master bored me to tears and I wasn’t able to finish them.
To be completely honest, I think Bunpro sentences and other resource’s example sentences are not good at all for learning a language, so I don’t and have never used them as the crux of my study plan. I simply focus purely on the grammar point and its basic function.
The good point of Bunpro is you can control the pace and it covers most of what is need to learn Japanese grammar to a decent level. Slow or fast, it doesn’t really matter how you do it, just how long you stick with it. My personal preference is to just get as much knowledge into my brain, and then process it through practice and experience with native Japanese materials later.
