Back on track, the experiment starts.

After 3,500 problems and 7 days I have an average rating of 1530 at CTS.
That´s exactly what I had when I left CTS a half year ago.
So efforts aren´t down the drain after all.

Now comes the interesting part at CTS.
I have done about 44,000 problems at CTS.
This means that I have repeated the problem window of 10,000 problems more than 4 times.
Usually after 4 circles is where calculating ends and pattern recognition starts.
And indeed I´m starting to recognize a lot of problems.
So let´s see where the 7 circles of madness leads me.

For the improvement from 1470 to 1530 I had to learn 2100 new patterns allready.
That took me 7 months and 44,000 problems.
So to master 1 new pattern you have to solve 21 problems at CTS.
This doesn´t look very effective.
The main reason for this is that the problemset is too big.
So it takes about 1.5 to 2 months to repeat the whole set of 10,000.
In the mean time my OTB rating improved from 1710 to 1750.

To improve further from 1530 to 1600 average rating at CTS I have calculated that I have to learn another 2300 new patterns.

  1. Wow this means taking a job serious. Good luck! CTS patterns are not from games, but from a random generator. They may occur in games, though, I remember one or two parallels in my own games and at CTS. But I also have the impression that CTS patterns are biased in some way. Often repeated motifs in different puzzles. Maybe this is one of the reasons I stopped using CTS. The other is that I have the impression that speed is not my problem, I rather try to avoid time trouble, and I do not intend to become a blitz champion.

  2. Mouse, everybody with 100 points more OTB is better than me in blitz too.
    So developing blitz-like skills seems to be unavoidable.

  3. Space,
    To calculate the amount of problems I did the following:
    1 problem at CTS = 1 pattern

    At CTS:
    Problems/Rankings look at the table with high rating.
    Press "next 20"
    In de adressbar appears the offset, which you can manipulate. So you can find the offset of a 1530 and a 1470 problem. Subtract the offsets of both problems from each other and you know the amount of problems between them.
    Another method is to estimate it from the bell curve.

  4. Space,
    it is not as strange as it looks. We are talking about CTS-rating points, which become less reliable at the edges of the bell curve. Lately Uraleech demonstrated exactly that.
    At the edges the relation between effort and CTS-rating improvement is far from linear.
