Just one more example, but this time with the costs involved in successful scan.

Percentage = 10 / 150 = 0.07

Planet Scan
-----------
ScanOffset = (1 - ( 1 * 0.07)) + 0.5 = 1.43
ScanChance = 0.5 / 1.43 = 0.35 * 100 = 35%

So on average the player has to scan the target 3 times to get a hit, which totals 9,000 res.


Unit Scan
---------
ScanOffset = (3 - ( 3 * 0.07)) + 0.5 = 3.29
ScanChance = 0.5 / 3.29 = 0.77 * 100 = 15%

So on average the player has to scan the target 7 times to get a hit, which totals 84,000 res.


Adv Unit Scan
-------------
ScanOffset = (7 - ( 7 * 0.07)) + 0.5 = 7.99
ScanChance = 0.5 / 7.99 = 0.06 * 100 = 6%

So on average the player has to scan the target 17 times to get a hit, which totals 408,000 res.

Summary
This may seem high for a new player to cope with, but I doubt they will be attacking someone with 150 dists in the first place, it will be newb v newb (someone of equal rank).

This also means that Alliance scanners are useful, but not a requirement.
