Perhaps it is possible to alter some of the values over time. Not RAW as there is nothing that mentions a specific mechanic, but....
Within the context of a wargame...
Resources might not change if I read what the value represents correctly, but if you have a high TL planet lose its TL 8+ status would that reduce its Resources value?
Labor could change over time if it is a simple computation of Pop-1. But what can destroy a population to reduce the UWP pop value by a factor of 1 or more? Hmmm.
Could Infrastructure and Efficiency be values which reduce as damage in a wargame situation?
