I'd like to suggest a change to the consumption rate of MSP of ships maintained at maintenance facilities from 'BP/4' to
5yr maintenance cost/5/4'.
As it is right now it is possible to design a ship that will cost less in MSP doing a full deployment then what it would cost to just sit in port doing nothing.
As an example this ship I have designed in my current campaign has a maintenance life of 5.40 Years a 5 year maintenance cost of 11,602 MSP and a build cost of 10,062.8 BP, the current 5yr cost of having it in port would be 10,062.8/4 = 2515.7 per year or 12,578.5 per 5 years, under the proposed change the cost would be 11,602/10 = 1160.2 per year or 5,801 per 5 years which is still more per year then the 1yr deployed but you also still don't run up the maintenance life.

In further as it stands one can build a 'mothball hangar' that would normally have an insane maintenance cost but can considerably cut down on the maintenance cost of other ships sitting in port, using one designed for the ship above we have:

which under the current system has a yearly cost of 3,967.7/4 = 999.725 per year which is a little over a 3rd of what the above ship is, under the proposed system it would be 174,641/10 = 17,464.1 per year
continuing with an example of a orbital defense station design: we have currently 27,584.8/4 = 6896.2 a year or 34481 per 5 years(which is a whopping 12.75 times the 5 year deployment cost), under the new it would be: 2,703/10 = 270.3 a year or 1351.5 per 5 years. Looking at it further sitting in port for it's entire maintenance life would cost 231,988.168 MSP which is 2.2 times what it would cost in a deployed state

For the Kestrel bomber 118.3/4 = 29.575 MSP per year in the current and 13/10 = 1.3 per year in the new, current: deployed 166 MSP over 19.24 years, in port 569 MSP in 19.24 years, proposed: in port 25 MSP in 19.24 years
For the Hangar we have 5,702.6/4 = 1,425.65 MSP per year currently and 378/10 = 37.8 MSP per year, current: deployed: 23,899 MSP over 43.04 years, in port 61,360 MSP in 43.04 years, proposed: in port 1,627 in 43.04 years
as it stands the more well engineered a ship/station/fighter is the more you are penalized for having it in port, this is counter intuitive and can leave players wondering why their new easy to maintain ship/station is stripping their planet of it's MSP as it is also not mentioned at all in the designing of ships/stations. only to find that the solution is to build a giant hangar with nearly nothing on it engineering or otherwise to house it in
PS: dividing by 10 was halfway arbitrary and should be considered more closely for balance and can also have tech line to increase efficiency, eg start at 2 then work on up to 10 or something like that
