I think this one the best Eternal map and among the best maps ever designed in style a la find the exit if you can. I wade through it near tree days when first played Eternal. Awesome complicated layout. Hard to find secrets. And I guess this map have no meaningless parts. 
But for speedrunning Excalibur is nightmare. Check out 41 tag. I was telefraged with the blue key in my backpack at least in 80% cases mostly by pinkies form 162nd sector. Please see Et30tele.lmp. Killing as many as you have BFG's charges can increase your chances, but only chances through. Revenants and spectres can telefrag too. Besides time over 9 minutes is guarantied after such fight. Et30-829 is my first exit without any shoot in the jump for the blue key room. After this spot mostly no problem. Romero's head's hole is huge. Except one moment, cacos and skeletons may lead more offensive defense of the pool with the last before exit stair.
If you do not try this map else, beat it now.
