Price to sales Advantage vs Disadvantage

From Schweser

Price to sales advantage

  • Sales revenue is not easy to manipulate or distort as EPS and BV which are significantly affected by accounting conventions

Price to sales disadvantage

  • While less subject to distortion, revenue recognition practises can still distort sales forecasts.

These are two contracticting sentences. Whats the real answer

no contradiction. Price to sales is not perfect but it is better than the others.
