Let me try to clarify.
Input file has many lines.

but all values should be separated by spaces.
As you can see, column 7,8, and 9 can not be separated in line 2, 4, and 5 because all numbers are stick together without space.
The reason is that the precision of the first 6 values are two decimal points after period, while that of last 3 values are four decimal points after period.
Such high precision of the last 3 values are used up the space separator between values.

As you said, there should be a space only after 33.99 and 18.9134 in second line, 31.20 and 17.2112 in 4th line, 23.92 and 16.8176 in 5th line..and so on.

Hope this is help for better understanding.
Thanks,

ANACRONTAB(5)						       Anacron Users' Manual						     ANACRONTAB(5)

NAME
/etc/anacrontab - configuration file for anacron DESCRIPTION
The file /etc/anacrontab describes the jobs controlled by anacron(8). Its lines can be of three kinds: job-description lines, environment assignments, or empty lines. Job-description lines are of one of these two forms: period delay job-identifier command @period_name delay job-identify command The period is specified in days, the delay in minutes. The job-identifier can contain any non-blank character, except slashes. It is used to identify the job in Anacron messages, and as the name for the job's timestamp file. The command can be any shell command. The fields can be separated by blank spaces or tabs. The period_name can only be set to monthly at the present time. This will ensure jobs are only run once a month, no matter the number of days in this month, or the previous month. Environment assignment lines are of the form: VAR = VALUE Spaces around VAR are removed. No spaces around VALUE are allowed (unless you want them to be part of the value). The assignment takes effect from the next line to the end of the file, or to the next assignment of the same variable. Empty lines are either blank lines, line containing white-space only, or lines with white-space followed by a '#' followed by an arbitrary comment. You can continue a line onto the next line by ending it with a ''. SEE ALSO
