Engineering DC to Divert Action?

[Prof.Dogg]

The example on p. 327 of the Corebook shows for the Engineer (Rose-7) to Divert Action to enhance Gunnery: "Since the PCs’ starship is tier 1, the DC of the Engineering check to perform this action is 17."

The rule on p. 323 though shows "Divert (Engineering Phase): You can divert auxiliary power into one of your starship’s systems, giving it a boost. This requires a successful Engineering check (DC = 10 + 1-1/2 × your starship’s tier)"

Which value is the correct base? 10 or 15?

[Belafon]

DC 10 + 1-1/2 x your starship's tier.

The DCs for many starship actions were adjusted downwards in errata/reprints, but the example was not updated to show the new DC.
