Just sharing to the process ofThe rules of scoring are designed to leave as little room for interpretation as possible, even if the result isn't always "fair" (especially to the pitcher). A lot of these (like "on the throw") have specific, defined uses, and aren't to be applied to other situations.
Regardless of "rule", I've always held that the benefit of any doubt or argument goes to the hitter.
That aslo suggests the questionIt would apply to whether to give a hit when answering these kinds of questions -
1. Would the batter have been safe at first if the fielder had gone to first on a fielder's choice?
2. Would the batter have been safe at first if the ball had been fielded cleanly?
Benefit of the double to hitter is part of the rules, although I don't know that it applies here.

It is my understanding the primary meaning 'benefit of the doubt goes to the hitter' applies to error/hit decisions.
As others have said, "advancing on the throw" is used for one runner advancing a base because of a throw trying to get a different runner out.
If the left fielder throws to the cut off, it's a double. (In this scenario, if the left fielder throws to the third baseman, it's still a double, because a throw to the wrong base is also not an error)

What rule am I making up?
I don't disagree that the play as described is a double. Where we might disagree is whether a runner who stops, then takes off and takes advantage of 'slow play' gets credit for a double.
