Expand on that please? I don't get the connection. Neither scale uses "pressure readings" from tornadoes...

After witnessing the continued decrease of involvement in the SpotterNetwork staff in serving SN members with troubleshooting issues recently, I have unilaterally decided to terminate the relationship between SpotterNetwork's support and Stormtrack. I have witnessed multiple users unable to receive support weeks after initiating help threads on the forum. I find this lack of response from SpotterNetwork officials disappointing and a failure to hold up their end of the agreement that was made years ago, before I took over management of this site. In my opinion, having Stormtrack users sit and wait for so long to receive help on SpotterNetwork issues on the Stormtrack forums reflects poorly not only on SpotterNetwork, but on Stormtrack and (by association) me as well. Since the issue has not been satisfactorily addressed, I no longer wish for the Stormtrack forum to be associated with SpotterNetwork.
I apologize to those who continue to have issues with the service and continue to see their issues left unaddressed. Please understand that the connection between ST and SN was put in place long before I had any say over it. But now that I am the "captain of this ship," it is within my right (nay, duty) to make adjustments as I see necessary. Ending this relationship is such an adjustment.
For those who continue to need help, I recommend navigating a web browswer to SpotterNetwork's About page, and seeking the individuals listed on that page for all further inquiries about SpotterNetwork.
From this moment forward, the SpotterNetwork sub-forum has been hidden/deleted and there will be no assurance that any SpotterNetwork issues brought up in any of Stormtrack's other sub-forums will be addressed. Do not rely on Stormtrack for help with SpotterNetwork issues.
Sincerely, Jeff D.

Pressure reading from several tornadoes are lower than that of most hurricanes.

But that's not related to damage...

I've seen low pressure from a "weak" tornado pull insulation out of a mobile home all around the roof.

The video and pictures I can pull up online aren't very impressive for an f-3. I was looking the the pictures that the NWS posted.
I live in BGM's CWA and am familiar with the 1998 tornado; while it was relatively weak over much of its path (and possibly not one continuous tornado at all), it did extensive damage (consistent with F3) to the home you're referring to in Deposit. I also remember seeing pretty significant tree damage near Rt. 8 and the Cannonsville Reservoir. My dad took me to see it several times since we only lived ~10 miles from there. The fact that the worst damage only occurred in a few isolated areas doesn't mean anything as far as the maximum rating is concerned.
As for the last part, everything you described sounds pretty well in line with what you'd expect from an EF1 rating depending on the construction quality of the home(s) in question.

No, no. That's a myth. Low pressure doesn't 'suck' insulation out. Winds blow it out.

equally all around the roof all the way around?

I don't know about insulation, but I do know tornadoes. So I get this one near Daleton, right? And I am way too close. I've got the vid on it right, I'm filming it. And all of the sudden outta nowhere, this sh**ty lookin' green Valiant comes pulling up right in the way. And this loser stumbles out of the car, he's got like a bottle of Jack Daniel's in his hand... And he just strolls up to the twister, says 'have a drink', and he chucks the bottle into the twister, and it NEVER hits the ground.
The twister caught it, and sucked it right up!

The suck zone. It's the point basically when the twister... sucks you up. That's not the technical term for it, obviously.
Sigh. Really?
The atmosphere doesn't care which direction the wind is blowing. Wind is generated by the pressure gradient force, so air moves towards low pressure or away from high pressure. You may think that means there is a semantic difference between "suck" and "blow" (insert Spaceballs reference here), but I'm pretty sure as far as the atmosphere is concerned it doesn't matter.

Exactly. The pressure difference didn't "suck" out the insulation. The wind does that...
Now if you want to semantics chicken-n-egg I suppose we could
but I don't think that's the direction calvin was heading

Off topic, but the egg came first. It's parents weren't exactly chickens, but evolution made those two almost chickens and created the first actual chicken. Now back to your regular programming...

That exactly are the forces that a tornado creates due to the low pressure, because there is outward pressure when a tornado passes overhead and one is in a building.

It wouldn't be StormTrack if a conversation didn't rely heavily on semantics.
Moot point anyways, because if you open the windows before a tornado hits, the pressure difference is equalized, and your insulation stays where it is. Bonus points if your house is built under a freeway overpass.

I think it only sucks out of the southwest corner anyways.
