I believe starbase upgrades (hull changes, that is) are counted as the full price of the new base (without the discount) in the queue's algorithms for calculating time-to-complete.

Can you check one thing?

Remove the partially completed factory and add a new factory above the new station.

Does it now show 4 years or still 5 years?

Theory based on further findings:

Stars rounds down each year when applying credit for partially completed items.
The rounding is down to an integer % complete.

For example, if you finish 999 resources of a 1000 resource item, stars gives you credit for 99%, not 99.9%. You'll have to spend 10 resources the next year, not 1.

In other words, for multiyear builds, you lose an average of 0.5% of the cost of the item for each year other than the year of completion.

How is this relevant? The base isn't partially completed in your current year.

When doing the calculation, you would have to add in growth of population (if any).

I have a test of a planet with SD upgrading to SS. The displayed resources on right side of build queue is 1035. The planet has 335 current resources and the stated build time is three years. 3 x 335 is only 1005, 30 resources short. Population growth in year 1 would be 26 extra resources, but not available until year 2. So it looks like it take multiple years of population production growth into the equation for long builds.

Have you increased any tech levels relevant to the dock or any of its components since building the dock? Are any of these components also on the SB? Have you checked for those components to be in matching slots for the upgrade (corresponding id locations)? Do you have IT, SS, ISB, GR, or BET?

Component upgrades don't matter. Hull upgrades don't matter.

PRTs and LRTs don't matter. Whatever the particulars of the upgrade, the queue will tell you the cost of the upgrade.

Just to note, I've never seen a queue that crosses 100 years.
