Interesting, I was not aware of the 91% vs 98% flaring vs combustion efficiency. Seems like a relatively recent finding based on the Ars article date.

You are correct in that many countries DGAF and just flare/vent the combined equivalent of multiple Texas's. Iraq, for example, flared 16.8 bcm (= 593 billion cubic feet) in 2018.
