Zero Delta using RDP to get Delta 1

[bubbacleese]

In the spreadsheet ship builder are you allowed to purchase Zero delta and let the +1 delta of the RDP give you a 1 delta ship? Or do you have to purchase at least 1 delta and get a bonus 1 if you have choosen the RDP role?

Enter Desired Engine Delta = 0 (the cell is red until you put something in other than 0.)

With role RDP selected and a 0 in the Enter Desired Engine Delta cell, the Value cell does read 1.

Page 92 of core rules:

All starships are required to have engines - you must purchase at least one
point of delta at this step.

I interpret that to be RDF will have a minimum of 2, because you must pay for at least Delta 1.

I would agree, if not, that is giving RDP yet another point of being the strongest role. Plus I really like that the ship builder spreadsheet shows RED when your purchased delta is only zero.
