Greetings,

I saw that difference of cost. Is it 150% more or 150% of the initial cost (50% more)? I am not English speaking born, so I don't understood this nuance in the text :

Initial ship cost 100.
Can you upgrade to 150 (50%) or 250 (150%)?

And once you upgraded, let's say it is 150 with an initial 100. And you upgrade again. Did the basis change to 150 or is it still 100?

Thank you
