Tornado intensity disparity between F- and EF- scale

Based on your interpretation of the Enhanced Fujita scale, do the professional meteorologists here believe that EF ratings will generally be assessed higher or lower than ratings on the traditional Fujita scale? The EF scale assigns more parameters to tornado damage and is more specific, but will the stricter criteria lead to reduced ratings?

I await the day when tornado wind speed can be determined while the tornado is active, instead of afterward from damage analysis. This way we could know the true intensity of tornadoes in rural areas that don't have the opportunity to cause significant damage. Are there any techniques for doing this in development to anyone's knowledge?

One of the tornadoes got an EF2 last week based on a 127 mph wind gust reported by a Mesonet station...I'm not sure if it had EF2 damage to back it up though...

research suggests that the old F-scale underestimated the lower rated storms and overestimated the stronger tornadoes. what does that mean? who knows...its still all subjective based on damage and not measurements.
