That means that they will look fairly simple to you.
If you can do the problems that cost you 10 seconds in a shorter time, your rating at CTS will increase. Finally, when you do all problems in less than 3 seconds, you will have the maximum reward.
So doing problems in 3 seconds in stead of 10 seconds is what CTS is all about.
From this arise three questions:
- How useful is this?
- Is the improvent from 10 to 3 the best or are other figures more efficient? For instance from 2 minutes to 3 seconds or from 5 minutes to 1 minute.
- Is CTS the best way to implement this?
Ad 2. About the 3 seconds part of the question: 3 seconds seems to be a reasonable time for the brainpart that is responsible for processing visual data and pattern recognition. If you ever want to give a simul this speed is necessary. Susan Polgar scored 2.4 seconds per move at her monster simul lately.
About the 10 seconds part of the question: I have no idea if this is best.
Ad 3. Using the theory of spaced repetition as ideal model, it is clear that the problemset at CTS is far to big and hence the rate of repetition is far too low.
After doing 2k+ problems last week my rating averages at 1510.
This is 40 points more than my start (was 1470) and 20 points less than my maximum (was 1530). So the 40k+ problems done in the past aren't totally down the drain after all.
