From the moment he began to record statistical information on his games, which was in June, 1980, Steven also began to record the number of times a seki appeared in his games. So far, up until the end of (a period that spans consecutive months) a total of sekis have appeared in the games that Steven played in that very same period of time.
Generally speaking, whenever a seki does appear in a game, it does so at the rate of one seki per game; however, on a few rare occasions--and the word "rare" deserves to be highlighted--some of Steven's games have had more than one seki in them. So far, the breakdown is as follows: Steven has played games in which only one seki occured of all his games), and games in which two sekis occured of all his games). This means that, all together, at least one seki has appeared in of Steven's games of his total, or, if rounded off, So far in his go career, Steven has never played a game in which three sekis appeared. (By the way, Steven, has never had a triple ko either. He sometimes wonders which one of these two rare phenomena -- a triple ko or a triple seki -- is the more rare of the two.)
(Take note that the current number of sekis that are declared to have appeared in Steven's games is a conservative count. Indeed, it's very much conceivable that, in some of his early games at least, especially when Steven was still a beginner, a seki might have been in the process of being formed when one of the players resigned before the existence of the seki to-be became obvious. Consequently, of course, in such cases the seki to-be would not have been counted. The possibility of Steven's not recognizing a seki in the making is certainly not inconceivable. Indeed, experienced players know all too well that when it come to the creation of sekis in their games, beginners are known to stumble into their creations accidently rather than knowlingly engineer their development purposely. This observation may help to explain the fewer number of sekis, relatively speaking, that are reported to have occured in the early years of Steven's carreer when compared to later periods).
Even though sekis have occured in of all of Steven's games, this should not be interpreted to mean that the distribution of sekis will reflect this statistical approximation, and that on a monthly basis a seki is likely to appear once in every 45 games. In fact, in two extreme cases, one in August, 2011 and the other in August, 2013 (see the bottom row of Table 1), Steven played, in each one of the two cases documented below, the highest number of sekis -- 5 in each month -- than in any other month of his carrer). (Parenthetically speaking, the total number of games played in August of 1211 and 2013 was 72 and 43 games respectively).
The information displayed in Table 1 is meant to be understood in the following manner: In the top row, for example, Steven had the historic expereince of having played in a total of months, or in of all the months that were available to him to play go, and yet, not a single seki emerged in that entire period of time.
When the information on the number of games with sekis is presented on a yearly basis, however, instead of on a monthly basis, as it was done above, then the yearly statistical percentage of games with sekis comes closer to the overall percentage of which, as it was mentioned earlier, is the overall percentage of games with sekis for all of Steven's games. The charts below displays this information.
In regards to those rare occasions when Steven plays a game in which two sekis appear, Table 2 provides some interesting information, especially on the gap of time separating the occurence of each game with two sekis. Statistically speaking, a game with two sekis is likely to appear once in every games, which, if consider the current average number of games per month to be games, then, statistically speaking, a game with two sekis should occur every 37.231 months, give or take. This figure transaltes into a more meaningful period of months, or, to put this figure into a more meanigful timeframe, the occurence of the next game with two sekis is like to occur in approximately years, monthS, and odd days.
* Game Number: This number is the one that is given to each game that Steven has played in his go career, in chronological order. Hence, the first game that Steven played in which two sekis appeared was his 3,273rd game. (Please note that when Steven documented each instance of a game with two sekis, he neglected to indicate which specific game in the playing session was the one in which the two sekis occured. Consequently, for the sake of convenience, he assumed that each instance of the occurence of two sekis always took place in the last game of each playing session.)
** No. Days: To calculate the time gap between each instance of two sekis, Steven used the date calculator found at the Web site Date and Time. When using the calculator prodived at this site, he never used the option "Include end date in calculation" in the calculation of the time gaps. The date of June 4, 1980 is the one on which Steven played his first official game of go ("official" in the sense that this game constitutes the beginning of his go statistics) and it is used here as the starting point in calculating the time gaps.
