As has been requested many times before, PLEASE use CODE tags when displaying sample input, sample output, and code segments. Do not depend on forum moderators and administrators to clean up your posts for you (hoping that we will guess correctly on how your data should be formatted.

Your calculations seem to assume that there will always be exactly two lines with a given 3rd field value. Are these pairs of lines always adjacent (as in your sample input and output)? Can there be just one or more than two lines with a given 3rd field value (and, if so, should the division be by 2 or by the number of lines with that 3rd field value)?

Why are you printing ten fields to your output file when there are only nine input fields? This is adding a trailing space to each line of your output file that is not present in the sample output that you say you want???

Does the width of any of your input columns vary, or are the column widths for each column constant for files this script will process?

   mutate_attributes ( args => $hashref, props => $hashref, type => 'str' )
       A hook for running a second command from within a command without having to use the commandline argument parsing.

       If "type", "uuid", or "primary_commands" are not passed in, the values from the previous command run are used.

   cmp_regex
       The regex to use for matching property key/value separators.

   $ID_REGEX
       The regex to use for matching the id argument (luid / uuid).

   setup_from_args
       Sets up this context object's arguments and key/value pairs from an array that looks like an @ARGV.

   parse_args @args
       This routine pulls arguments (specified by --key=value or --key value or -k value) and properties (specified by --props key=value or --
       key=value) as passed on the command line out of ARGV (or something else emulating ARGV) and sticks them in "args" or "props" and "prop_set"
       as necessary. Argument keys have leading "--" or "-" stripped.

       If a key is not given a value on the command line, its value is set to undef.

       More complicated separators such as =~ (for regexes) are also handled (see "cmp_regex" for details).

   set_type_and_uuid
       When working with individual records, it is often the case that we'll be expecting a --type argument and then a mess of other key-value
       pairs.

       This routine figures out and sets "type" and "uuid" from the arguments given on the command-line, if possible. Being unable to figure out a
       uuid is fatal.
