Yes, I can elaborate: It sounds to me like you are misting more then the chams may need. But, then again, I don't keep veileds so this could be perfectly normal to keep them healthy.
The reason people should care is because this much misting at those frequent intervals could create mold and/or mildew issues inside a house, which could pose a health risk to people. Mold is a serious issue and if the automated misting system is in anyway saturating drywall or wood in the room through the screen mesh, then the potential for growing mold increases. It may seem far-fetched, but there have been serious consequences to mold spores in homes over the past few years.
A lot of this would depend on the misting system itself. if it is an extremely fine mist and a very low volume (or usuage) of water, then the potential for mold decreases. However, many people have tried rigging-up "outside" misting systems for use indoors, and this is when the volume may be a little heavy for indoor applications.
I do know that this would be too much mist for Panthers or other chams that do not need this high of an increased humidity level as it could potentially result in respiratory problems for the chams.
Just my $0.02...
