One I've used for years is simple. Shutter speed should equal focal length at least, even with VR. It's true that VR helps but it's not to override Basic principles of obtaining sharp images.
There are people out there with more money that knowledge on the topic and will happily be upset with results created by their own foolishness at times. It will happen topside mainly I guess when not shooting flash.
We expect so much of VR and it can and does help, but better to apply principles that have been used for years.
Try and stationary subject with flash I'm sure it will be perfect.
