Description

Base detection from task forces is the maximum 10% in virtually all cases. The formula is:

round(10% * (1-0.5^(0.1* <detection sum of present TFs>)))

The displayed default base detection is calculated against an enemy with visibility 2/2, i.e. less visible than any practical task force.
Still, a single CV1 with detection values of just 9/4.5 produces

round(10 * (1-2^(-0.1 * (9*2 + 4.5*2)))) = round(8.46%) = 8%

base detection in this case, which is already very close to the maximum 10%. Task forces in ports are counted as well, as long as their fleet is assigned to the strategic region.

Steps to Reproduce
- split out a single CV1 into a seperate fleet
- assign the fleet to a region
- observe 8% Base detection in region
- add a second task force with any ship to the fleet
- 10%
