ChessTempo June 2014

rockyrook blitz problem rating 5.31.14 to 7.1.14
I've been keeping a pretty good eye on my chesstempo performance since January 2012.  I track several aspects including my monthly minimum rating, maximum rating and median rating per every 20 blitz problems.  So after I completed my 620 blitz problems for the month of June, I realized a few things special about this month.

Since January 2012, I've only ever been above a 1750 rating once (1752.6 in July 2012).  In June 2014, I hit 1759.6.

Since January 2012, I've never stayed the entire 620 problems above the 1700 mark.  In June 2014, I managed to stay above 1700 from start to finish.  My minimum rating per 20 problems was 1706.8 with the median rating coming in at 1740; which by the way, my median rating was the first time above 1730.  The previous best was 1721.9 in May 2012.

Another insight into the data shows that I took longer to solve the problems.  But I seem to be finding the right amount of time for any given problem, else if I were taking longer on every problem, then my rating would have gone down.  The average of my average recent time per problem has gone from 47 seconds in February 2014 to 62 in June.

My percentage correct wasn't special.  I came in at 81.29%.  That is slightly below the 2014 average for me.

Of course, June could be one big anomaly and July will see a return to "normal" - which is entirely possible, especially given the fact that I'll be on vacation for 3 weeks - which disrupts my daily routine.  But, if I'm able to keep the rating and percentage correct relatively high and the trend continues, I might be looking at something significant in my chess improvement with regards to chesstempo.


  1. Your blitzperformance is seemingly not improving. Since a few weeks richard did erase the duplicate reward reduction. Since this time you dont get "punished" if you solve a problems you already did see before. You already have "Problems Done: 36042" but in "your range" are just a few thousand problems at CT. So you have already seen most of the problems several times.Even if you dont recognise that it still raises your score at these problems.

  2. that's a good point Aox, but I was still curious to understand why in *June* I saw the bump in rating as opposed to April and May - even though I've been consistently solving about 20 problems per day. so I posed the question to Richard on the CT forum. my post and his reply here: http://chesstempo.com/chess-forum/messages_from_admin/duplicate_reward_reduction_removal_for_most_users-t5453.0.html;msg45043#msg45043

    he makes some good points - I truly do tend to think the main reason for the increase is that I've been getting a higher volume of higher-rated problems AND I've been successfully solving them. However, I don't deny that the duplicate reward reduction has played a bit into this.

    according to Richard, about half of the 36K problems I've attempted are not duplicates. and of the duplicates only about half (9K) I've seen more than two times.
