Question about Luck advantage: Do you re-roll all three dice? - Page 2

The Luck advantage lets you "reroll a single bad die roll twice and take the best of the three rolls!".

I was looking at this page with probabilities of success with 3d6 in GURPS, and they provide a special table for Luck rolls at the bottom. I did my own analysis and the values they list match what you get if you're allowed to reroll all three dice.

My intuitive interpretation of "a single bad die roll" is the roll of one die, not all three. But...

The GURPS basic set never explicitly defines "die roll", but does define a "success roll" to be a type of "die roll", and that a success roll involves three dice. This suggests that the "single roll" referred to by the Luck advantage includes all the dice used for a particular roll, and not only a single die.

Which is the correct interpretation? Is it all the dice included in a roll (e.g., all three for a standard success roll), or is it just one die involved in the roll, no matter how many dice are used?
