Dyad 1.0
That was my original intended solution. The "more efficient" way is slightly easier, but only slightly, and I couldn't figure out a way to force "the Krogglidor way", so I left it as is. Your blind playthrough is impressive. You seemed to get all the concepts very quickly. Have you played Omnicoder's or anyone else's four portals maps before?
By the way, Mek, did you figure out the letters? If you gave up, I'll just tell you here.
what the letters mean
M = medium/moderate
H = hard
They represent the three difficulties of the Aperture Science theme.
I can imagine you might be at a bit of a disadvantage if you aren't used to thinking in English (not to insult your English).

No, I have never played a 4 portal map before this was my first one, and also I managed to beat it in 3:58 by fixing the mistake that nrnoble pointed out to me, it can be found here.

JackSafari has explained it to me but thanks. I would probably have never figured that out on my own

Released here!

Dyad in 3:58
Nice speedrun. I can get about 4 minutes, but unlikely I'll beat your best time.
If you want a challenge and a way to reduce your time even further, it is possible to get the the duel gun with one super fling from the slanted panel that propels you all the way across to the other side(not part of the original design). It is pretty cool, It works very similar to the super fling in Portal's Chamber 07, and just as difficult. I've done it three times so far, but I have a failure rate of 90%. I'm trying to get it work during a speedrun. So far the three times I've done it have been during practice attempts.

Like this, or did you have something else in mind?
skip to gun
If I use this I expect to be able to get my time down to 3:30 or so if I tried

I think your youtube url is broken. It won't play back. Even when I try the youtube ID '0uacx0h8EI' manually, it does not work.
I do not know what is wrong, http://www.youtube.com/watch?v=_0uacx0h8EI works for me...
Edit: my bad I did not realize the "_" was part of it sorry about that.

skip to gun
That is a good way that I had not considered, but it is not the way that I was suggesting.
The way I did it was coming out of the portal on the slanted panel (opposite the entranceexit) so fast that I am able to grab the gun and skip off the platform to the other side. It's hard to do, but the results in completing the entire chamber in about 10 seconds or less. Getting the required speed is easy (like Portal's Chamber 07), it is timing that is hard so that you can grab the gun and bounceskip off the platforum to reach the other side (exit).
I will make a video.
Getting Duel gun with a single Fling:
This is an example of getting the duel gun with a single fling. The timing is very difficult, and so far I have not gotten a full speedrun that include its. I finally got this one example after at least 50 failed attempts. It is repeatable because I have done it 3-4 times during practice attempts.
Dyad Chamber-E Advanced Solution
This is an advanced ninja solution to Chamber-E. To be very clear, Mevious's designed solution is significantly easier, and can be accomplished using basic Portal skills.
This method has a very high failure rate; I can do this about 1 in every 50 attempts because there is no margin for error. It has to be done perfectly or it fails.
