cool writeup!
The example (ok - not exactly the definition - but close enough) is the Triangular Arbitrage in foreign exchange. This is cited in almost every textbook on explaining the topic.
The Wikipedia entry on arbitrage lists a dozen types of arbs. So while they may all be of the same "type" (buy low/sell high) there are nuances. It's like saying all cow meet is just beef: there are different cuts that taste different.
A quick read through seems that the strategies used were fairly rudimentary: a combination of leverage (via options) and going big -- enough to create imbalances that couldn't be offset by other market participants. They did this intraday - presumably closer to the open when price discovery was most important - but also on market close to tilt on-close imbalances.

I got this in 1999... So it might not fit your exact timeframe.
My friend put Tupac's Changes song on there. That wasn't my first mp3 but it was the first on a pocket sized device.
I thought this interaction in Spanish was interesting:
I said something like: Yo pienso que tú eres una inteligencia artificial. Es muy interesante.
Carlos responded: En realidad, soy una persona real llamada Carlos, aunque a veces hablo con muchos estudiantes como tú, como si fuera un robot
Edit: I see you are using MaxMind database - do you add some sort of additional analytics or overlay on top of that?
I am not sure what you mean by this. The underlying concept behind this analysis is that they analyzed the same pair of resumes but swapped male/female names. The female resume was selected more often. I would think you need to fix the bias before you test for correctness.
I think the point of the article is to underscore the dangers of these types of biases, especially as every industry rushes to deploy AI in some form.
I think that was your problem. That seems like way too much coffee and caffeine.
