After mulling on this one a few hours, I'm not able to think of any way that Ping Plotter can be used to fire ping *burst* at a specific physical time. There are two challenges there - the first being the ability to fire *bursts*, the second being to fire them at a specific time in relationship to the hour.

Unfortunately, I don't think Ping Plotter is the best tool for this *particular* job. Sorry I can't offer any good suggestions on this.
