Given the following dataset:

Run 1 Run 2 Run 3 Run 4 Run 5
1.991 1.871 1.885 2.007 2.114
2.009 2.211 2.199 2.281 2.094
2.018 2.091 2.115 2.241 2.020
2.782 2.105 2.506 2.660 2.273
1.501 1.885 1.921 1.235 1.873

…and the following series of Vim commands:

gg qq j0 :s/⎵/⎵+⎵/g y$ A ⎵=⎵ <C-r>= (<C-r>")/5⏎ <Esc> q @⁠q @@ @@ @@ :2,6sort /[=]/⏎

• gg: Jump to the top of the file
• qq: Begin recording a macro into register q
• j0: Drop down a line and back to its first character
• :s/⎵/⎵+⎵/g: Substitute every space on the current line for a plus sign
• y$: Yank (copy) from the beginning of the line to the end
• A: Append text onto the end of the current line
• ⎵=⎵: Type an = sign with a space either side
• <C-r>=: Enter the expression resgister (calculator)
• (<C-r>")/5⏎: Put the contents of the pasteboard inside of (<pasteboard>)/5 and run it
• <Esc>: Leave insert mode
• q: Stop recording macro
• @q: Run macro q on the next line
• @@: Run the last macro (i.e. q) again
• @@: Run the last macro (i.e. q) again
• @@: Run the last macro (i.e. q) again
• :2,6sort /[=]/⏎: Sort lines 2–6 based on the value that appears after the = sign

That will leave you looking at this:

Run 1 Run 2 Run 3 Run 4 Run 5
1.501 + 1.885 + 1.921 + 1.235 + 1.873 = 1.683
1.991 + 1.871 + 1.885 + 2.007 + 2.114 = 1.9736
2.018 + 2.091 + 2.115 + 2.241 + 2.020 = 2.097
2.009 + 2.211 + 2.199 + 2.281 + 2.094 = 2.1588
2.782 + 2.105 + 2.506 + 2.660 + 2.273 = 2.4652
