First, the good news, I finished in the money (ITM) in 7 of them, this is a 47% ITM and my average finish was a whopping 28/100. To give you an idea of these numbers, based on data from the excellent site thepokerdb excellent players in the long run have ITM numbers of 15-20% and 40/100 average finish. My own numbers in the long run should be around 17% ITM and 38/100 (Not my numbers in thepokerdb site, since they track only PokerStars tournaments) .
The bad news is that even the numbers above are nice, they are not really that important, the statistic that really matters is ROI; basically how much money are you making per tournament. This last week I spent $3079 in tournaments and I won $3342.49; so, for the week I won $263.49 for a very disappointing $17.57 per tournament.
Of course this is a small sample, but my numbers for the year have been pretty similar. Barring the luck factor, these number help you to analyze which parts of your tourney stages play may need a tune up.
