Having a configuration where a single node is configured in "Settings.ServerTest.NodeIds.Static.AllProfiles.Scalar" set of nodes, e.g. Float.
 
The code "/library/ServiceBased/MonitoredItemServiceSet/CreateMonitoredItems/writeToDeadbandAndCheckWithPublish.js" at line 33 is not applicable in all cases:

     // wait 1 sampling interval cycle
     publishHelper.WaitInterval( { Items: item } );
if( publishHelper.Execute() ) {
.....

The WaitInterval before the publish is ignoring:
 

1. The sampling interval might be revised, therefore item.RevisedSamplingInterval is a better choice
2. The sampling interval, even if it is not revised, should include an extra delay to compensate for systems with less-strict timing, for example when value updates depend on underlying PLC's which are sampling at certain rates (ex:100ms).
