Colors distinguish the student progress information displayed. The horizontal axis is runs.
Highest fact, Run high fact
The highest fact a student has started is plotted. Most students will shoot up into the fours or fives and then level out while they get faster. Flashcard has detected their speed capabilities and they are learning over at a faster pace.
The highest fact answered in a given run is shown by a dashed line. This can be below the highest fact line because beginning students
are learning over to answer faster. This line can also be below the highest started fact line because there are too many long breaks between runs and the shorter-term memory gains are being broken before becoming longer term.
Accuracy
Accuracy is determined by the number of facts answered in each run less 1 for a wrong answer, -1/2 for a corrected answer, -1/2 for a Faster message, and -1/4 for a Faster message. Most students will have accuracy percent from the upper 80s to mid 90s. Accuracy tends to drop a bit as new facts are started, then goes back up.
Answer speed
Answer speed is plotted as the 25th, 50th, and 75th answer-speed percentiles. Please see The Speed Graph below for more information about answer speed.
The answer-speed lines tend to be a bit wild at the start as the student and Flashcard get used to each other. The 75th-percentile speed can be off the screen. Within a few runs to a couple weeks student answer speeds will begin heading steadily towards 1 second. Most students will get all 3 percentile speeds under 1 second with regular practice.
Remembrance
Remembrance is a measure of how-many-facts are known how-long. This is also the student score. The buildup of remembrance is exponential because it is about the same to go from 1-minute memory to 2-minute memory as it is to go from 1-day memory to 2-day memory. The first minute, hour, and day are the hardest and require frequent successful repetition opportunities without long breaks or days off. Then it gets easier after two-day successful recall. Required review becomes less frequent than once every two weeks for most facts.
The Speed Graph
Answer speed is timed from question display until the first answer keystroke. Flashcard tracks a recent average of answer speeds for each fact. These answer speeds are shown for each fact. The facts from 0 + 0 to 100 / 10 are the horizontal axis from left to right.
The 25th, 50th, and 75th percentile answer speeds are also shown. 25% of facts are answered faster than the 25th percentile, 50% of facts are answered faster than the 5oth percentile, and 75% of facts are answered faster than the 75th percentile. These percentile speeds are plotted historically on the Trends graph.
Flashcard reviews slow-answered facts more often.
The Due Graph
The facts from 0 + 0 to 100 / 10 are the horizontal axis from left to right. The vertical axis is time but the scale varies. The vertical distance from the crosses to 'Now" indicates how soon a fact will be asked again.
The fact-cross colors indicate the length of time from when a fact was last asked until that fact will be asked again. The facts have this same color coding when asked during a Flashcard run.
