Quote from yoshifan:
Recently I've been trying Easy and Normal the most, but I would like to try running all four of the difficulties. Competition is perfectly welcome, of course. 
Starting today I'm recording every attempt I make, since these kinds of runs have so much potential for unexpected events. But besides hoping for good setups, my efficiency could also use a bit of work. I tend to leave a column of viruses on the left or right side near the end, so that I end up wasting more capsules than if I had worked evenly. Of course, making your enemy retire is the best way to save time, but I think efficient habits can really make a difference, since you can't end every battle early.
In the meantime, here are my current best times:
Easy - 8:12
Normal - 14:44
Hard - 21:01
S-Hard - 25:22 (no deaths!)
It's hard to set particular expectations right now, but I think 8:00 would be a great target for Easy.

This is an astounding accomplishment. Levels 8 and 9 on S-Hard are unfathomably difficult. In years past, I didn't record myself playing, so I gave it a try just now and watched it afterward, only focusing on what the computer player is doing. As I was watching level 8, I said to myself "How do I possibly win this? He's putting the pieces down lightning fast with no major errors." The only thing I noticed was a high number of moves that caused a lot of drop-lag (or whatever it's called when your own pieces fall a long distance from a dangling clear).
I managed to beat him in 4:21 with only 12 extra pieces on my screen (a full virus pill being counted as 2 pieces).
Next, Vampire Wario. My deathless run was quickly ruined. I was annihilated on my first attempt. Watching it on playback, I am not sure it was possible to have won. The speed and accuracy and intricate combos he made were just not matchable by human hands, eyes, and mind.
After a few more tries, I decided to just set up an umbrella on one side, since I do not see how one can survive his relentless combos at lightning pace. This worked, but it took 6:50.
A couple interesting notes on Vampire Wario on S-hard (and probably hard also, I just haven't reviewed it to see): He does set up some very dangerous combos on which you could deliver a deathblow if the piece falls on the dangerous center tile that he has piled one from the top. I then said to myself, "Yeah but I probably didn't have anything resembling a combo." but that isn't true, I had one set up, and it was a simultaneous clear combo also.
Also, as incredible as the AI vampire Wario is on S-Hard, the algorithm is broken (I assume intentionally?) when it comes to endgame, as there are two glaring weaknesses:
1) A complete inability to attack from the bottom up, which is necessary for him if you managed to ruin one side early with combos, and
2) A baffling tendency in endgame to repeatedly make the best move relative to the colors on the board but irrelevant of whether the pieces being cleared are actually viruses. I watched as he just kept making intricate combos with new pill pieces but wasn't clearing any viruses.
