What Is Memory Resilience? The Scheduling State VocaX Keeps for Each Word — Not a Score, Not a Ranking

Memory resilience is a state VocaX keeps for every word: the steadier you are with it, the later the next review is scheduled; miss it once and the word is called back sooner. It is not a score and not a ranking, and it does not fall on its own because you skipped a few days. The one thing you can do with it is see which words are still fragile and which have settled, and spend your limited time on the fragile ones first. It is only a display of a scheduling state — not a judgement on your ability, and not something you can convert into "how much longer you will remember this".

1. The one-sentence answer: it is each word's scheduling state

"Resilient" here means one thing only: is this word holding steady right now, or has it gone fragile? A steady word is left alone for longer; a fragile one is brought back sooner.

It is not these three things, and knowing the difference saves a lot of confusion:

• Not a score. It does not climb because you show up often; frequency on its own carries no information.
• Not a ranking. It describes this one word. It does not put you next to anyone else.
• It does not decay on its own. Skip a few days and it will not be a little lower each morning — see the next section.

Memory resilience answers exactly one question: is this word steady right now, or fragile? Steady words come back later; fragile ones come back sooner.

2. When it actually changes

Only one thing moves it: you actually practised the word. Recall it and it shifts towards steady; miss it and it shifts towards fragile. The three practice formats — translation, dictation and speaking — each keep their own record, which is why practising only one format keeps a word in the queue indefinitely.

None of the following will move it:

• Time passing. Leave it for days and it still shows what it showed the last time you practised it.
• Browsing the entry. Opening a word's detail page, playing the pronunciation, reading a passage — none of it counts.
• Marking it "secure" yourself. That is a note to yourself; it changes no scheduling.

So you will notice something slightly odd: a word you have not touched in ages still shows the resilience it had last time. That is not a missing decay — we simply did not want to turn it into a health bar that drains on its own. "This one is due" is expressed by the review time, not by a number that gets recomputed every day.

Time passing does not make resilience fall. It updates only after you have actually practised a word — "this one is due" is left to the review time to express.

3. What you can do with it

• Pick out the fragile words. The ones showing low resilience are where your time is worth the most right now.
• Confirm which have settled. High-resilience words will not keep showing up in the near term, so you can hand that time to others.
• Set up one focused pass. Flag the words you miss as you go, then work through them together later — see Flags Turn Mistakes Into Signal.
• Decide whether to change practice format. If a word is steady in translation but fragile in dictation, dictation is the side that needs the work.

When a word comes back is decided by the review schedule the app sets; for the trade-offs behind that timing, see How Review Timing Is Calculated.

4. What it is not

• Not a judgement on your ability. It describes where one word stands right now, not how well you are learning.
• Not convertible into "how long you will remember it". High does not mean the word is yours forever; low does not mean your earlier work is wasted.
• Not something you can grind up by browsing. Only an actual answer moves it.
• No cross-format compensation. Doing well in translation will not pull the dictation line up with it.
• Not a number that changes daily. We do not build a "daily memory score" — if a number changes while you have done nothing, that change tells you nothing about your memory.

Memory resilience is only a display of scheduling state: not a judgement on your ability, and not something you can convert into how much longer you will remember a word.

FAQ

Is memory resilience a score?

No. It is the scheduling state VocaX keeps for each word: steady words come back later, fragile ones sooner. It does not accumulate, and it does not rise because you show up often.

I have not opened the app in ages — why hasn't it gone down?

Because time passing does not make it fall on its own. It updates only after you have actually practised the word. Whether a word is due is decided by the review schedule, not by this display.

I marked it "secure" — will it go away now?

No. That is a note to yourself; it changes no scheduling. The only thing that makes a word appear less often is actually practising it to the point where it holds.

Can I browse it repeatedly to push the number up?

No. Opening the entry, playing the pronunciation and reading the context do not count. Only an actual answer moves it.

What should I do about words with very low resilience?

Just work through the review order the app gives you, and do not drill the same word yourself; flag the ones you miss and go through them together later. Re-brushing a word the same day does not help — getting it right straight after seeing the answer is recognition, not retrieval.
