I mainly use the Bunpro order because the example sentences for every grammar point are written so that they include examples of previously learned grammar points too. But that won’t work if you “skip ahead”.
For example, say I happen to know an N2 grammar point but my overall level is N5. If I add the N2 grammar point to my reviews, the example sentences I’ll be getting will include various N4 and N3 grammar points which I won’t understand! So I’ll be unable to comprehend the examples without help and will thus miss out on one of Bunpro’s coolest features.
That said, because I’ve picked up various grammar points from various sources outside of Bunpro, I do find it beneficial to jump around and add those to my reviews whenever possible (so I’ll be able to practice them). But whenever I do that, I first read all of the example sentences to make sure that I can understand them (meaning they must not include too much “advanced” grammar). If I can’t, I bookmark the grammar point but don’t add it to my reviews.
