If you're stalling at around 30% ... well, three possibile culprits come immediately to mind. It's possible that A) You're not using Heisig's method correctly -- B) You're trying to go much too quickly, or C) You're not truly locking the kanji into even your short-term memory before hurling the flashcards into the SRS's vault.
I know we all learn "differently," and everything ... but there are elements to the way that the human brain works that are absolutely universal to all of us, and Heisig taps into that (we're using a triple-pronged attack of IMAGERY, VERBAL mnemonics, and LOGICAL arrangement ... that covers all bases, and it was designed that way). Unless you're literally autistic or dyslexic (which it doesn't sound like you are), 80% should be something that's very easy to maintain.
So, why are you getting 30%? As I stated above:
1) You may not really be using Heisig's method, and only THINK you are. Are you just going through the order of the kanji as laid out in the book, without creating your own imagery/stories/mnemonics for them? Are you actually WRITING the kanji that you learn? It's just that ... a 30% recall rate is the sort of thing that might happen if you were just reading the kanji in the order he presented in RTK1, but relying on plain old drill-and-repeat memorization for your recall.
Remember that Heisig's method is to apply MENTAL IMAGERY and repeat a VERBAL STORY to yourself, AS YOU WRITE. If you're not doing all three thrings, you're not using the method. If you're not literally saying to yourself "a small Sun and a huge Moon make a very BRIGHT sky" as you write the "bright" kanji, and literally picturing it in your mind's eye as you scratch it down ...
you're not actually using the method. You're using some hybrid of it you came up with, and it sounds like it's not working so well.
2) You're trying to go at the speed of light. Heisig is fast, yes, but if you're only spending 10 seconds per kanji, I doubt anyone but Lt. Commander Data could keep up. Spend a minimum of 1-2 minutes per kanji. It's about what I do, and it's plenty for me. You may need more, and of course ... some abstract kanji will take longer.
3) You're not performing any reviews at all before adding flashcards to the site. Your very first review should NOT be the one scheduled after three days in the first box. You should do at least one review of all the kanji that you learned at the end of a study session ... if you can't remember one of them, then you haven't actually finished yet. The day ends when you recall all the kanji that you allegedly "memorized" within that particular session.
That way, you're assured that you've got it in short term memory. Only then (in my opinion) should you add them to the site's SRS at all. Come back the next day to take them out of the "never reviewed" column, and the spaced repitition truly begins.
I may be somewhat new to Heisig, and granted, I'm still short of the half way mark ... I've got to say, though, that a 30% recall would indicate to me that I did something wrong with initial memorization ... I would be suspicious that I "missed" a step somewhere.
If you're thorough in the beginning, when you're just barely adding the new kanji ... the foundation for long-term recall becomes that much more solid. I've never failed to get above 80%, even on the longest-term reviews. Not once. In fact, the first time I got below 90% (just a few days ago) on some cards in the second box, I was seriously bummed out. I didn't understand how typical of a recall rate that was for the first big "hump" in an SRS program, but now that I see how common it is ... I feel better.
I think the key is to make sure you've got them seriously drilled into SHORT-TERM memory, before adding the flashcards at all. You review for the first time the next day (from stack 0 to stack 1), then three days out, then seven, and so forth ... the site does the scheduling for you.
It's a beautifully effective procedure, and I love it dearly ... you just have to know how to apply it correclty. Don't worry ... you'll get there. It's also entirely possible that your actual problem isn't related to any one of the three issues I've listed above .. I'd bet a lot of money that you're at least dabbling in one of them, however.
