Hello!
Recently I (re)discovered LingQ. I think it’s a fantastic study tool, and would like to express my gratitude to all the people who make it possible.
Among other things, I appreciate the abundance of #statistics to keep track of one’s learning. One of those statistics is the #streak : the number of consecutive days you’ve been reaching your daily goal. This is supposed to be a measure of #consistency. But is it?
Imagine you take part in a 90-days challenge. You reach your goal every day for 88 days and miss the 89th. You resume on the last day, and winds up with a streak of 1 day. Is this a good indicator of your consistency throughout the challenge?
Somebody who learns every other day would have studied in total 45 days and would end the challenge with a 1 day streak - just as you did. Somebody who didn’t study for 88 days and started on the 89th, would end the challenge with a streak of 2 days - twice as well as you.
These examples are deliberately far fetched. But I’m sure most learners struggle, sooner or later, with a broken streak.
The point is the validity of an indicator. How well does a statistic measure what it is supposed to measure? Does the metric tell us what we think it does? There is no easy answer.
We also expect a good indicator to motivate us. From what I can read in the forum, broken streaks tend to upset people. It puts pressure on their shoulders, not necessarily in a good way. The longer your streak, the more you have to lose in case of a breach.
I believe it should go the other way round: if you reached your daily goal for 89 days in a 90 days period, a common sense measure of your consistency would be 89/90. This indicator decreases as you skip your daily routine, and increases as you stick to it.
There is no single answer to the problem of measurement. So, I’d like to ask: which indicator, if any, do you use the most in your study? Do you find streaks beneficial to your consistency? Which other measure would you suggest?
Thanks for the brainstorming! Happy learning!
