Dyad 1.0
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.
Question about this one, do you crouch and jump off of the podium? If so you are probably unknowingly ABHing.
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.
I never even considered finding a new way to do E better, like you said once "it was pointed out to me that there was a betterquicker way to [do the chamber]. I can't believe I didn't see this one myself because now it seems so obvious."

He would have to be, there isn't really any other way to keep that momentum.

As far as the first one where I get the gun, it doesn't require crouching and crouching seems to cause it fail more frequently (don't reach the other side), but I have done it while crouching. I use the same method that I use to in Portal's Chamber 07 (http://www.youtube.com/watch?v=hgMSjtFMQ5E), thus how it is accomplished is not done 'unknowingly'. Months ago when I finally figured out Chamber 07, I discovered that ABH doesn't always require crouching, which is demonstrated in my Chamber 07 video and in the video where I get the duel portal gun. In both cases, I wasn't crouching. Scripts weren't involved because I don't use scripting.
My advanced ninja solution for Chamber-E does appear to require crouching otherwise I hit the overhanging wall or hit the front of the stairs. This backward fling requires crouching, a perfect angle, and momentum to reach the ledge. Normally I don't like such difficult flings, but since Mevious's design solution doesn't require it, its perfectly fine as a ninja solution.

Well you are kind of half doing ABH, you can't speed up like that (very much at all) but if you hit jump at the right moment then you will not lose any velocity, I am not sure if Mevious would like that solution though (I don't know if he would consider that a glitch) and since it is his map I would like to play by his rules for speedruns.

I didn't know Mevious had speedrun rules. What are they?
There are generally no rulse for speedruns, but the map author could prefer you to not use glitches.
Pretty much this.
As far as I know Mevious does not have "rules" but he has stated he does not like glitches so I would prefer not to use them for speedruns in his map.

It is actually much simpler. It simply is a backward fling.
Even if I don't like a glitch, it's fine if you use it, especially for speedruns. If you do some really easy trick that lets you skip half of the level, that's another story, and I would be likely to release another version with that possibility removed. However, none of the stuff so far has been either easier to find or easier to perform than my solution. My goal as a designer is to have you discover my solution first (which you did, Krogglidor), then find your own alternate ways of completing the level.

You are officially the best mapper ever.
Edit: just don't expect me to not glitch the CRAP out of your map now.
Edit 2: ARG! you make your maps to glitch proof. D:
