Hi, I'm checking source code for percentile calculation: There is a descrption, showing there is 19 groups: https://github.com/axboe/fio/blob/master/stat.h#L89 Below it there is macro showing group number to be 29. #define FIO_IO_U_PLAT_GROUP_NR 29 https://github.com/axboe/fio/blob/master/stat.h#L112 I'm wondering if the original intent for setting FIO_IO_U_PLAT_GROUP_NR was to 19 and what I see there is just a typo. Please let me know.
