Script Preparation code:

var s1 = "28.9% CPU samples were in `Array.Sort` called from `DiagService.Controllers.PerfCPUController.CpuTask`. We expect this value to be less than 0.7%."

Tests:

Split
var resultSplit = s1.split[1];
Substring
var resultSubstr = s1.substring(s1.indexOf('`') + 1, s1.indexOf('`', s1.indexOf('`') + 1))
