I've got a specific anki deck where I have around 350 cards that I'm reviewing and 260 new cards that I haven't touched yet. I'm behind on my reviews for this particular deck (put it off for a while), so while, for instance, I can review the 350 cards + 10 new ones per day (give or take), that doesn't really make a dent in my new cards list. Would it be beneficial for me to increase the number of new cards learned to speed up getting through the pile of new cards? Or could it end up being harmful to my vocabulary retention?
I realize that this may be a little too opinion-based; I'm just looking for any general guidelines or rules of thumb for an "optimum" number of new cards to learn everyday, if it exists.
I don't have any deadline that I'm working towards, for reference. These flashcards aren't for school or anything, so I can take as much/as little time as needed.
