Isn't an order of magnitude 10x? According to your link they spent $12.74 billion in 2016.

Not necessarily, it could be e if you're using natural logarithms. Anyway: log10(12.74) = 1.10, log10(80) = 1.90. So, it's a little less than a full order of magnitude, but pretty close.

Although not normally used for smaller amounts it can go in both directions. ~1/10th is still an accurate if archaic use of the term.
