Iron Chef America – Margin of Victory

by A.J. Coltrane

Looking at the wikipedia page for Iron Chef America results — it seems like there have been a lot more blowouts the last few years. Here is the Victory Margin, as a 7 episode rolling average:


Looks like a trend to me.


I removed all of the team competitions and all episodes that used four judges. The chart goes through the end of Season 9.

Ignore the spike right at the start — Morimoto defeated Roberto Donna 50-33. Donna only completed two of the five dishes. It always kind of bugs me when I’m reminded that they gave Donna another chance; a second chance doesn’t feel very “Iron Chef” to me.

The other big spike is during Season 8. I wonder if the level of competition changed, or the judges really changed, or the new Iron Chefs have a much different talent level, or… what else?

The average margin of victory has gone from about 4 to about 6, I’d have to think that’s at least partly on the judges.

    I am assuming that this is just margin of victory regardless of who wins, correct. It would be interesting to see if the same trend holds if you break out the Iron Chef’s victories and the challengers victories into separate graphs.

    Correct, the graph is absolute margin of victory, regardless of who wins.

    Iron Chef victory margins and challenger victory margins could be the next post. I already have that broken out.

    I think either a rolling Iron Chef winning %, or a cumlative winning % would be intesting as well — the rolling win% wouldn’t have the “ballast” of the cumulative total and might be more… volatile, and therefore a more interesting graph.

    Cumulative +/- might be worth a look too.

    The spike towards the right hand end is what gets my attention. I’m guessing maybe Steingarten didn’t work those or something(?)

    Maybe the margin of victory has more to do with the chefs. Two of my favorite chefs were the in the first three episodes. Much like the Top Chef contestants they are really reaching at this point to find quality chefs.
