Hi all, Jetstress can run for 24 hours or more?

Sure, but I don't think there's much to be learned by running it that long.Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

The default is 2 hours. As Ed suggests, I don't see any benefit in running it over longer periods.Alexei
