Here is a different approach. I start by creating a statistics object:

Statistics = Struct.new :count, :sum

stats = Hash.new {|h,k| h[k] = Statistics.new(0, 0)}

File.foreach "foo.dat" do |line|
if /^\s+\b(.+?)\b\s+(\d+\.\d+)/ =~ line
s = stats[$1]
s.count += 1
s.sum += Float($2)
end
end

Note, you might have to tweak the regexp.

Kind regards

No, it doesn't. It's hitting the inside wall.

The sfx people on this show are lazy and incompetent and likely
Canadian. It's still hitting the inside.

Yes, because it hit the inside.

Yes

It hit the inside. There was no point at which it remotely looked like
it hit the outside. They said who the pilot was, they said he was
leaving Chesters Mill, the guys on the ground inside the dome saw and
heard the plane headed for the dome from inside, the plane hit the
inside of the dome, the plane came almost straight down almost hitting
them at the edge of the dome (which would mean it wasn't very high).

They clearly have, but that doesn't have anything to do with the fact
that the plane was inside.

I don't know what you mean by "sloping away from", but I remember
that sequence clearly, and the plane was inside the dome.

You don't need sophisticated arguments here: the debris of the crash
fell inside the dome, so the plane must have been inside the dome.

Yep. But it does raise the question of how large the dome is, given that
it apparently encompasses an airfield of some sort along with the town
and whatnot. I suspect that, especially given a second season already,
this dome's footprint is going to get larger and larger over time...

Heh. I noticed something similar when the butterflies were all
collecting on the *outside* of the dome while the image of them
certainly appeared to have them collecting on the *inside*. But I spent
so much time ripping on major flaws with that particular outing that it
felt like piling on to bring this up, as well, at that time.

In the book, the airfield was elsewhere. The plane was being flown by a
flight student and her instructor. The student was the wife of one of the
Chester's Mill town selectmen and they were flying over the town when the
dome came down because she wanted to see her home from the air. But the
actual airport from which they took off wasn't inside the dome's confines.

Well, it's possible that the airfield is outside THE DUMB and the guy's
flight path took him through THE DUMB as it appeared.

Yeah I remember noting that one of the butterfly shots was odd.

I was annoyed that they claimed there shouldn't have been butterflies at
all, and yet there they were on the *outside*

Indeed, that seemed to me far and away the most likely explanation
when I saw the crash.

For heaven's sake, I know that from the storyline the plane is
inside the dome. The title of this thread is "More Dome Dumbness". Just
take a look at the opening sequence, Use your eyes. If you can't see it
in real time, record it and look at it in slow motion. The plane flies
into the outside of the dome. The CGI guys made a mistake.

Yeah, I didn't consider the possibility of it just being rotten timing
for the poor pilot, so this is clearly not a legitimate complaint point.
