Random Stargate SG-1 observation.

Just recently I've been ripping my Stargate SG-1 DVDs so as to watch the episodes on my iPad.

I can't help noticing - and I don't know if this is something that's been observed, commented upon, or even explained, by the fandom - that each episode is exactly 42 minutes 26 seconds long.

It must take quite a lot of effort to ensure that level of uniformity...
