What i noticed about this is that the amount of points required for the slot depends on the number of slots you have and it is always based on the LOWEST type of slot you have I.E:

My F-15 S/MTD had 33 slots in all areas, i needed about 8k points to hit 34 but , from 34 onwards the amount of points jumped quite a bit to the 40k range.

My B-2 on the otherhand had 35 points in arms and body but only 29 on misc, and to upgrade it i needed 4k then 9k.

The conclusion: Up to 34 slots you can upgrade quite fast and after that it takes very long, but what dictates the points threshold is the smallest type of slots that you have.
