Ok first try on a formula (yes its not KISS so dont bother telling me).

Percentage = Amps / Dists

ScanOffset = (ScanID - (ScanID * Percentage)) + 0.5

ScanChance = ( 0.5 / ScanOffSet ) * 100

ScanID:
1 = Planet Scan
2 = Development Scan
3 = Unit Scan
4 = News Scan
5 = Incoming Scan
6 = Jumpgate Probe
7 = Advanced Unit Scan

So on to some examples:


Amps = 10, Dists = 20

Percentage = 10 / 20 = 0.5

Planet Scan
-----------
ScanOffset = (1 - ( 1 * 0.5)) + 0.5 = 1
ScanChance = 0.5 / 1 = 0.5 * 100 = 50%

Unit Scan
---------
ScanOffset = (3 - ( 3 * 0.5)) + 0.5 = 2
ScanChance = 0.5 / 2 = 0.25 * 100 = 25%

Adv Unit Scan
-------------
ScanOffset = (7 - ( 7 * 0.5)) + 0.5 = 4.0
ScanChance = 0.5 / 4.0 = 0.12 * 100 = 12%


Amps = 15, Dists = 20

Percentage = 15 / 20 = 0.75

Planet Scan
-----------
ScanOffset = (1 - ( 1 * 0.75)) + 0.5 = 0.75
ScanChance = 0.5 / 0.75 = 0.66 * 100 = 66%

Unit Scan
---------
ScanOffset = (3 - ( 3 * 0.75)) + 0.5 = 1.25
ScanChance = 0.5 / 1.25 = 0.40 * 100 = 40%

Adv Unit Scan
-------------
ScanOffset = (7 - ( 7 * 0.75)) + 0.5 = 2.25
ScanChance = 0.5 / 2.25 = 0.22 * 100 = 22%


Amps = 20, Dists = 20

Percentage = 20 / 20 = 1

Planet Scan
-----------
ScanOffset = (1 - ( 1 * 1)) + 0.5 = 0.5
ScanChance = 0.5 / 0.5 = 1 * 100 = 100%

Unit Scan
---------
ScanOffset = (3 - ( 3 * 1)) + 0.5 = 0.5
ScanChance = 0.5 / 0.5 = 1 * 100 = 100%

Adv Unit Scan
-------------
ScanOffset = (7 - ( 7 * 1)) + 0.5 = 0.5
ScanChance = 0.5 / 0.5 = 1 * 100 = 100%
