I am using the HdrHistogram_c and getting strange results. Just wanted to check if I am doing something wrong. I use the hdr_value_at_percentile function to periodically log various percentile numbers (50,75,90,99 etc) along with max, min and mean. I dump the complete log using hdr_log_write when the program terminates, then use hdr_decoder to convert it into a CSV. The percentile numbers in the CSV file don't match the ones I get using the hdr_value_at_percentile function. Any ideas on how I can figure out what I am doing wrong?
