hah.. runway rumble is one of those weird effects that didn't blow up if you set the value higher than 1.0 in the original configs and I think there were some aircraft that had that set as the default.
One of the new aspects of this new UI is that the settings sliders can be made so that they only offer a useful range, even though they display %0-100.
So many of the usable effect intensity values are in the 0.1-0.2 range, that the sliders are actually applying a scaling factor under the hood to 1.) only provide a usable setting range and 2.) give more granularity inside that setting range.
So there are some artifacts like that (%750) on a few of the old default values.
