Default Re: [Spaceships] Paying more for better system?

So I've been going through these suggestions with more care and have a couple comments.

With sensors, any bonus to Scan *IS* a bonus to range, since the primary use for high skill is to offset range penalties. There's no need to have separate bonuses here.

I'm not a rocket scientist, but it seems that a 20% and 40% boost in delta-v is unrealistically huge. I'm having a hard time finding any accurate numbers for realistic rockets over the years, but my gut just tells me that it's not right. Most rockets using the same fuel have Isp within 10% of one another, and delta-V is just Isp multiplied by the Ln of (full mass / empty mass); most increases in delta-V come from reducing empty mass of the entire rocket by tiny fractions, and those mass savings can come from anywhere from computers to better structural materials for the fuel tanks.
