Austin is full of rooms that call themselves a spa, and not one of them has a verified outcome on file. So this map does not tell you which is best. It tells you what each room is for, which is the question a stranger is actually asking, and it leaves the ranking seat open until somebody earns it.
An engine returned this Hargraves Drive room for the spa question in the July diligence pass. Which engine is not recorded, so we do not print one. It is on this map because most of the spa answers Austin gets point somewhere else entirely, and this one is in the city the question asked about.
A Research Boulevard address that sits in the part of town the north-side spa query actually covers. An engine returned it; the aggregate status is stored and the engine behind it is not, which is a limit of how that pass was recorded rather than a judgment about the room.
A Ranch Road 620 address carrying an Austin line, named in the diligence pass with no engine recorded against it. We print what we hold and nothing more, and what this book holds on the spa head is thinner than on any other question in it.
