The values are computed using the equation sum(1/i for i=1 to n), where n is the number of capturing players, a harmonic number. This equation is derived from the source file trigger_area_capture.cpp that is available as part of the Source SDK. Values generated from WolframAlpha using the input Table[1/HarmonicNumber[n], {n, 32}]

Previous experimental results

These decay rates were determined by creating a map with a 100 second capture point, then using Puppet Bots to capture said point. I am unable to derive a simple equation that explains these values. These times were generated using a SourceMod script as follows:

#include <sourcemod>

public Plugin:myinfo =
{
	name = "Capture Timing",
	author = "Org",
	description = "Console out debug info",
	version = "1.0.0.2",
	url = "example.org"
};

public OnPluginStart()
{
	HookEvent("controlpoint_starttouch", Event_StartCapture)
	HookEvent("teamplay_point_captured", Event_EndCapture)
}

public Action:Event_StartCapture(Handle:event, const String:name[], bool:dontBroadcast)
{
	new Float:time = GetEngineTime()
	PrintToServer("Control Point Entered : %f", time)
	return Plugin_Continue
}

public Action:Event_EndCapture(Handle:event, const String:name[], bool:dontBroadcast)
{
	new Float:time = GetEngineTime()
	PrintToServer("Control Point Captured: %f", time)
	return Plugin_Continue
}
