Notes

Metrics

• There are two metrics that describe spelling a word: speed and accuracy
• Speed (r) of spelling a word is letters/second
• Accuracy (k) is the expected number of attempts until success
  • Success is defined as consecutively matching all letters exactly
• The game keeps score of attempts and time per word
• Expected Time (T) = A * len(word) / r
• Expected Attempts (A) = k ^ -len(word)

Spaced repetition

• Wikipedia

  "Spaced repetition is a learning technique that incorporates increasing intervals of time between subsequent review of previously learned material in order to exploit the psychological spacing effect. Alternative names include spaced rehearsal, expanding rehearsal, graduated intervals, repetition spacing, repetition scheduling, spaced retrieval and expanded retrieval."
