Ok, first let me get the facts straight:

2) Given a perfectly straight, slightly concave roadway on a low humidity day, what kind of general distance increase would a 1-2dB increase in sensitivity result in?
3) Would a 3dB increase in sensitivity mean that the RD can now detect signals only half the power of the previous lowest detectable signal level? Or does 3dB of "sensitivity" not translate to 3dB (or double) "power"?
4) Is it that if the lowest detectable (alerted) signal power is, say (randomly selected) 0.5mW, that a 3dB increase in sensitivity would mean 0.25mW signals will now be alerted to... but because 0.25mW is so close to 0.5mW, and considering how fast the signal attenuates in free space, that the typical increase in initial alert distance is pretty small in real-world conditions?
Thanks for sharing your expertise. I'm just trying to quantify what this increase in sensitivity really means to the driver, and whether it's worth the trade off of reduced Cobra falses (due to the 6-10dB decrease in sensitivity to brief CW signals) in POP ON mode.
