Most of my daily reviewing is coming from the last stack. This is a big chunk of studying time spent on cards I'm pretty much consistently getting right.

Could I consider the 4th stack learnt and to now put the time into other forms of study/reviewing kanji that really needs it?

The 4th stack is not the last stack, if I recall the method correctly. It's just that all the latter stacks are shown on the same bar.

Is there a point when the the cards just stop expiring? Because there's a bit more motivation to review them with an end in mind, as opposed to a never ending cycle.

If you rate them as easy they come back in a longer interval. Eventually you'll find that you don't really need to review all that often anymore, and you can just drop the site for sentence study or whatever.

According to a spaced repetition system, the items will always expire at one point or another. The system does not know what you do with the material outside of the system's reviews. So for a typical SRS, it assumes you will forget the information if you don't review after a certain amount of time.

But unless you want to pass the KanKen or so, if you know you get enough kanji practice... you don't have to clear expired cards all the time. I leave mine to expire in big chunks of hundreds of cards and clear them out once a month or so... I forget some due to lack of review but in those case I've found a simple refresh of the story is sufficient.

My point here is that once you finish RtK it's not a big deal if you don't review in time or forget some characters, the meat of the work is done. I still like to continue to improve some stories, but that's just enjoying checking out people's stories and replacing those that I've lost a "connection" with, i.e. stories which I no longer relate to.

The items you know well should end up coming up for review only once every few months, so the number should end up being very few per day.

I finished just over a month ago, and I average just about 25 reviews per day now, which doesn't take long.

Ahh, that's what I wanted to hear.

Hm, I'm averaging at around 80 per day. Used to be 100, but perhaps that means it's gradually dropping.
