Anti-missile hit probability

[Jorgen_CAB]

Could it just not be that the ASM have an ECM rating of 30 and therefore the chance of hitting become less then zero and that this simply is not displayed in the to hit chance even though it probably should?

At least this seem like the most likely explanation.

I think ECM should be emphasised in the to hit as it can be very decisive at times.

In my example, the target missiles have ECM on them, and the displayed hit chance correctly considered it.

Ah... yes... I saw you wrote that after my post...

But could there be a problem with the log and what it show IF the ECM reduce the to hit below zero... perhaps should test that if that was not done?

Unfortunately, that is not the case. If the expected hit chance is below 0, the AMMs won't auto fire at all.


AMM:

Code: [Select]

Missile Size: 1.0000 MSP  (2.50000 Tons)     Warhead: 1    Radiation Damage: 1    Manoeuvre Rating: 100
Speed: 20 000 km/s     Fuel: 610     Flight Time: 10 minutes     Range: 11.55m km
Cost Per Missile: 2.5502     Development Cost: 255
Chance to Hit: 1k km/s 2000%   3k km/s 666.7%   5k km/s 400%   10k km/s 200%

Target:

Code: [Select]

Missile Size: 3.00 MSP  (7.500 Tons)     Warhead: 0    Radiation Damage: 0    Manoeuvre Rating: 10
Speed: 40 000 km/s     Fuel: 1 675     Flight Time: 18 hours     Range: 2 556.3m km
ECM Modifier: 60%     ECCM Modifier: 60%
Cost Per Missile: 9.00     Development Cost: 900
Chance to Hit: 1k km/s 400%   3k km/s 133.3%   5k km/s 80%   10k km/s 40%

Hit chance in theory:
20000/40000 - 60% = -10%

Whats interesting here is that it looks like despite deciding not to fire, one of the launchers still had a maintenance failure. Is that WAI?

@Zeebie, I suggest you submit your DB with this bug to the bug report, as we have ruled out the most obvious possibilities...
