I just added 20 points to my personal record at CTS: 1616.
So I finally passed the 1600 mark!!
My estimated average rating at CTS improved from 1470 to 1570.
100 points is a substantial improvement. Enough to base conclusions on.
Problem solving at CTS results in a higher CTS rating.
Maybe you smile about this, but I remember very well in the early days that we saw no significant improvement by guys with 10K+ at CTS. So I nearly quit because of that. But my infamous crude calculations convinced me that 10K is way too little to see significant improvement. I'm glad I managed to hang on.
The second conclusion, about what it will do OTB, will have to wait. It is vacation time now, so no rated games ahead the next two months.
