The post exposure prophylactic treatment is actually only a single dose.
The 72 hours in the link is from time of removal. The 72 hours I reference is how long it typically takes for a tick to regurgitate into a host (it has to feed for some time before it regurgitates). The article referenced it as being engorged. The correct answer is in the middle. It takes 72 hours for the tick to regurgitate, but it could technically crawl off a dead host and on to you. But it's harder to identify if it's engorged. These facts led us to use the doxycycline while the lab confirmed if the tick was positive and how long it was feeding.
