Severus frowned slightly. "No, Reginald, it simply means he will not have at least an 80% chance of recovery. If I modify the eigenvalues and solve for the outcome being his survival, then..." He flicked his wand and the line moved rightward as a percent chance of survival over time. It began at 100% at the current time, which made Severus glad to realize his equation was working (since Harry was alive at this point) but the line wavered over the first few hours and faded around a 35% chance after five days.
