Todd, I feel your pain. Fire pump test reports have turned into frustration for me.
A pump fail is when the fire pump is unable to supply the system demand(s). The report should show the actual performance test results, certified manufacturer curve, and the adjusted curves one one graph. Most pump reports I see don't provide this necessary information. If they provided all 3 curves on the graph, that will answer any questions. Something sounds wrong with the information provided to you. A 5% drop is not a fire pump failure. An investigation should be completed to figure out why the pump test results have degraded. An increase at 150% is suspect and question their results.
