Great plan! All these long, thrilling levels belong to my favorites, and I'm looking forward to watch your fascinating demos on them. Same for dew's and Memfis' PRCP stuff.
Will surely record in an upcoming future:
HR2Final.wad MAP15 UV-Max in less than 11 minutes
Pl2.wad MAP29 in less than 20 minutes (less than 15 minutes is basically impossible, I think...maybe even if TASing)
But I have to disagree about the "time limit" on PL2 map29. These large, action-filled maps always have a large margin for increasing the monster killing efficiency, especially when there is a BFG (because a thorough maximization of the BFG damage is a radical time saver). I think a TAS demo for this map (if played as tightly as jongo's PL01-123 or Andy Olivera's ET11-539) will be under TEN minutes.
Yep, I have always considered Vile's MAP29 demo to be spectacular even for his masterful ability. Strange that his LV29-405 and Anders' LV25-129 haven't been nominated for Cyber Award 2003.
Beating Belial's Deus Vult MAP02
Beating Never_Again's TNT MAP21
Beating Okuplok's Sunder MAP14
Beating stx-vile's Doom2.wad MAP29
But while his run is really smartly played, there are still possibilities to bring it down to 3:XX. For example, you can kill the mancubus near the last lift with SSG (without losing neither time nor cells), and use plasma on both of the final two barons.
Belial's and Okuplok's demos (for DV02 and SU14) are also excellent, but they have more margin for improvement. And EV211156 shouldn't be that hard for you to beat by 2 minutes or so.
As for me, my near-future plan is realizing some of my "dream demos" -- optimizing some UV Max, UV-Fast, Nightmare runs on various difficult epic levels. First of all, MM2 MAP28 -- yes, still busy with it, as I'm aiming for a MUCH better time than 11:XX (which I have originally planned). I completely recalculated my sequence of relocations, my ammo management, etc. After returning to Germany (on May 1.), I'll be more free than before, and will work on it more actively.
But in-between spending hard work on "dream demos", I may keep producing some short, spontaneous, lazy, "easy-fun" runs :-)
Here are my latest Doom speed demos, and here is the archive of my records done in 2005-2016.
