What this is:
I call it a match chart. It shows the locations of all the
first hits in a particular match.
What is a first hit?
A first hit is the first hit of a confrontation, which likely leads into more moves to string a combo. Because almost every melee combo involves tech chasing, following DI and has certain frames where the opponent can escape but might not, I defined a combo as any string of hits the opponent falls into that allows him less than 10 frames to shield, run, or otherwise defend himself other than teching or using "get-up" options.
Note: I did not include projectiles as a first hit, but if they were followed up I counted the follow up as a first hit.
Process:
I first drew the stage on a whiteboard as accurately as possible. I used mewtwo's rolls, which happen to be ~exactly 1/3 of the size of dreamland, to divide the stage into thirds. I used that to determine the starting and stopping points of each platform, with some minor approximations and estimations.
Next, I watched the match and marked each first hit location in marker.
Finally, I copied the stage and marks over into photoshop.
What can this show us?
This can show trends in where players (and by extension, their character) like to choose their fights. By viewing the points it should be fairly clear where certain characters have advantages (where they hit the opponent) and where they are disadvantaged (where they get hit).
Flaws in the process:
The biggest flaw is that this was done by observation alone. I looked at my gamecube screen for stage size/proportions, and I looked at the video for the instances of the hits.
The next biggest flaw would be the distortions between video to whiteboard and whiteboard to photoshop. It is difficult to get exact locations onto the whiteboard, and the distortion grows when you have to transfer the points a second time.
Another flaw would be that the points are inexact. In places where multiple conflicts occured, I put the dot slightly above or next to the one already there.
Also, I admit my photoshop image isn't the most pretty, but I don't think that takes away from the information in the slightest.
Dr. PeePee vs Lucky, Game 3
To be noted, there are 17 first hits for Dr. PeePee and 20 for Lucky. The match started late, with lucky at 51% and PP at 5%. I counted the first utilt by PP until the ending dsmash by lucky.
Note: I did not include a double hit near the end of the match where PP sh naired and lucky jabbed (afterward, PP retreated while Lucky approached with a nair), this conflict happened in the center of the stage.
Dr. PeePee got 8 platform first hits and Lucky got only 5. On the ground Dr. PeePee got 9 first hits with Lucky getting 15. The difference in numbers is because Lucky was using the platforms to evade Dr. PeePee, forcing Dr. PeePee to attack him on the platforms when possible. On the opposite end, Dr. PeePee had control of the ground level with the lasers and spent most of his time on the ground, thus being hit there more often.
So what can be concluded from this? I think it can be safely concluded that neither character is completely safe in any spot on the stage. I think its fair to say that ground level gives slight advantage to falco while fullhop/platform height gives slight advantage to fox. I think both elements are important to the total match-up, and neither is stronger than the other unless yourself as a player let it be.
