NPR Labs results seem to dispute HD supporters claims

A significant listener base extends beyond the 60dbuv contour.

NPR data seems differ from HD promoters claims that all FM listening is extremely local, in very strong signal areas only.

Let's clarify:

"(Public radio broadcasters who often occupy these lower-frequency FM Channels know that a significant listener base extends beyond th 60dBuV contour..."

1. Define "significant"

2. They are talking about Public Radio stations below 92MHz.

Let's also look at this in context: They're trying to eliminate interference from FM modulators (those seemingly overpowered devices that Satcasters and iPods use) so of course they're going to add that "aside" to their report. When they enter these "facts" into a debate about IBOC, then it becomes relevant.

significant - fairly large.

Those slimey, disgusting, murderous, DXers better not try listening beyond the city grade coverage in the commercial band, eh?
Facts are facts or else they aren't facts. Facts are never relevent unless HD supporters say they are, and then they are surely not really facts at all, just more smoke, mirrors, and HD hype.
My dictionary says - significant=important. Of course that definition is not from the new, revised HD edition.

The HD rollout just began a few days ago, (plus 3 1/2 years):

I believe in always directly wiring the FM modulator to the antenna input of the radio in the car (or through a coaxial switch). I set my FM modulator (and all my FM presets) to the frequency of my favorite local FM station. As the station is not ingressing into my system, It has been determined that my signal is not egressing to the outside world. At any rate, the strong local station overpowers my signal right around where the shield on my coaxial cable meets the black polywhatever insulation wrapped around it. I am confident that a properly installed system will never create any issue for the owner or the road neighbors. Installations where signal radiates from one antenna to another should never be done.

Exactly. The "in-line" modulator systems work exceptionally well, and work by injecting RF into the antenna input of the radio. Unfortunately, these often require professional installs so instead you see the "antenna to antenna" solutions, simply because there is no install required. Of course, then you hear some static, consumers complain, and the manufacturers are tempted to crank up the juice a bit. Then you have the problems that we're dealing with now...

People have complained to me about getting QRM'd all over the place, people who leave their modulators on 88.1. My area (Southeast Florida) has two stations on 88.1, this little college freshman and this mighty voice of God. I intentionally chose a frequency with a fairly strong local station just so that any incidental radiaton from my clean system will be covered within a few inches EEKS, don't click there!! Simply astounding what one can stumble over in a simple web search!
