Theory

To study your memory and sleep, use options available in SuperMemo in the following places:

• Workload
• Analysis
• Statistics
• Element statistics
• Timeline

Examples

Tools : Workload

You can use Tools : Workload (Ctrl+W) to inspect the daily and the monthly calendar of repetitions. You can view the number of repetitions scheduled, number of scheduled topics, number of scheduled items, as well as the record of past repetitions, and past retention, or how many new items were memorized.

Daily workload

SuperMemo: Tools : Workload : Daily tab showing the record of repetitions executed over a two-month period

Monthly workload

SuperMemo: Tools : Workload : Monthly tab showing the record of repetitions executed over a three-year period

Tools : Statistics : Analysis

You can use Tools : Statistics : Analysis (Ctrl+Alt+I) to inspect your forgetting curve, daily changes to your measured forgetting index, your learning overload, and many more:

Forgetting curve

SuperMemo: Tools : Statistics : Analysis : Forgetting Curves graphs for 20 repetition number categories multiplied by 20 A-Factor categories

Daily changes to the measured forgetting index

SuperMemo: Tools : Statistics : Analysis : Use : Efficiency : Forgetting index shows you the changes to the measured forgetting index on individual days

Priorities missed due to overload

SuperMemo: Tools : Statistics : Analysis : Use : Priorities missed : Topics shows your actual processing capacity for high-priority topics on individual days

SuperMemo: Tools : Statistics : Analysis : Use : Priorities missed : Topics shows your actual processing capacity for high-priority topics on individual days

Tools : Statistics : Statistics

You can use Tools : Statistics : Statistics to supervise and understand your learning process:

SuperMemo: Statistics window that you can use to inspect the main learning parameters of your learning process

Tools : Statistics : Element data

You can use Tools : Statistics : Element data to inspect learning statistics of a given element:

Element data window after executing a repetition on an item about the Pascal programming language

Tools : Timeline

You can use Tools : Timeline (F12) to optimize the timing of your sleep as well as the timing of your learning:

Sleep and repetitions timeline

Inspect the timeline of repetitions and sleep:

SuperMemo: SuperMemo: Sleep and repetitions timeline displaying repetitions blocks of the current collection (in red) and sleep blocks (in blue)

Look for the best time for learning or sleep (see Timeline for details):

Alertness

See how your brain gradually loses its power during the day:

SuperMemo: Tools : Timeline : Alertness graph makes it possible for you to visually inspect how grades decrease during the waking day. It also shows the impact of circadian factors with grades slightly lower immediately after waking and slightly higher after the mid-day dip in the 9th hour

Two-component sleep model

Look for the time of the day that should give you maximum learning power. See when your learning is not likely to be effective and when you should rather go to sleep:
