A band this wide is itself the finding. When independent methods land far apart, they are reading a business whose value depends heavily on which lens you apply — volatile earnings, heavy reinvestment, or an asset base that cash-flow and asset-based methods score differently. That disagreement is information: it says the choice of method matters more than usual for ATR. Treat the median as one reading among several and compare the individual models below before acting.
