The other should be printed as it is..
This should fix it.

Code:
awk '{ 
  for (i=2; ++i<=4;)
    c[i,$i] = f[i,$i]++ ? c[i,$i] += 0.1 : 0 
  }
{ 
  for (i=2; ++i<=4;) 
    $i = sprintf("%.1f",$i -= c[i,$i])
  }
 9' infile

NAME
pr - print file SYNOPSIS
pr [ option ... ] [ file ... ] DESCRIPTION
Pr produces a printed listing of one or more files on its standard output. The output is separated into pages headed by a date, the name of the file or a specified header, and the page number. With no file arguments, pr prints its standard input. Options apply to all following files but may be reset between files: -n Produce n-column output. +n Begin printing with page n. -b Balance columns on last page, in case of multi-column output. -d Double space. -en Set the tab stops for input text every n spaces. -h Take the next argument as a page header (file by default). -in Replace sequences of blanks in the output by tabs, using tab stops set every n spaces. -f Use formfeeds to separate pages. -ln Take the length of the page to be n lines instead of the default 66. -m Print all files simultaneously, each in one column. -n Number the lines of each file. -on Offset the left margin n character positions. -sc Separate columns by the single character c instead of aligning them with white space. A missing c is taken to be a tab. -t Do not print the 5-line header or the 5-line trailer normally supplied for each page. -wn For multi-column output, take the width of the page to be n characters instead of the default 72.
