guesswidth guesses the column position for fixed-width formats(fwf).
The output of the ps command has no delimiters, making the values difficult to machine-readable.
guesswidth guesses smarter than just space delimiters.
guesswidth is guessed based on the position of characters in the header. So having a header will give you better results.
There is also a guesswidth command.
