Today I had a closer look at my performance at CTS.
I did a series of 70 problems. I had 15 errors. The average solving time from the other 55 problems was 8.4 seconds. During the solution of the problems I counted the problems that I recognized. Much to my surprise that was close to 100% of the problems!
So the problem is not that I have not memorized the patterns, since I have.
The problem is that my braincells still need 8.4 seconds to release the answer at average!
That's why my rating doesn't increase at CTS while I learned more patterns.
The question arises if this is a matter of stockpiling the patterns in the wrong memory or is it a pre-phase of storing them in the right memory?
