He's referring to another thread. Currently, in settings.txt the following 2 lines exist:

Retrofit Cost Percent For Comps := 120
Retrofit Cost Percent For Comp Removal := 30

The first one makes you pay 120% to add a new component. This one is ok since you should pay a premium to add a component after the ship is built.
The second one makes you pay 30% of the cost of an old component to remove it. This one has some issues.

This means that if there are, say, 5 levels of a type of component, and each higher level costs more than the last as is typical, then it is actually cheaper to upgrade from level 1 to level 5 than to upgrade from level 4 to level 5. This is because of the second line above (i.e. you are paying 30% of something more expensive).

I think it's a little backwards. I would expect more time/effort/cost (real life work and money) to upgrade something that is VERY obsolete than to upgrade something that is SOMEWHAT obsolete.

Given that these are the only 2 moddable lines (not counting cost of the components) that affect this aspect of retrofitting and that the other retrofit mechanics are hard-coded, this can't be adequately addressed in SEIV unless there is another patch to the exe. But it can be brought up here for SEV.
