This report seems highly inaccurate. Hands in which the hero has stack size of 160 are put in the category large stack 115-150, for example. These mistakes can be made obvious by applying a filter "150 < stack size < 250" over the report. Then, while 227 of these hands are correctly categorised as big stack 150-250, another 4 are incorrectly categorised as large stack. I suspected these hands might involves stack sizes of between 150 and 151. This turned out to be the case, as when I narrowed the filter to 150 < 250, these hands dissapeared.
It seems that the report rounds every value downwards to the nearest one. However, this is not very useful to me as I mainly play tournaments, especially turbos. I can use the filters but it is so slow to observe my performance at one stack size at a time. Is there any way to get the report to work?
