Lowest pressure ever recorded in a tornado

There have only been a handful over reliable pressure measurements in a tornado, most of which have been courtesy of Samaras and his turtles.
 
Nice job Tim!
100mb of pressure drop: so it means that the pressure inside of the tornado fell down to nearly 800-850mb..It could be inteesting to know the real value of the pressure inside.
 
We should encourage everybody to put a barometer (and a flashlight) in his/her storm shelter, with instructions to note the initial, minimum, and post storm pressure. That ought to produce some data and perhaps a new record or two. It will also let the occupants know when it is safe to come out (after the pressure has gone back up).
