I've noticed a significant error with the ER Large Lasers. The heat difference between 1 is 2 has been very signicant. I did some tests. In all instances I was at a complete stand-still, and waited for my heat to be at 0% for at least a second before I fired again. Here's my results.

On my raven (12 SHS):
--Map 1
If I fire 1 ERLL I go from 0% to 7%
Expected for 2 ERLL: 14%
Actual: 27%
Disrecpency: 13% additional heat
--Map 2
If I fire 1 ERLL I go from 0% to 6~9%
Expected for 2 ERLL: 12~18%
Actual: 25%
Disrepency: 7% additional heat
--Map 3
If I fire 1 ERLL I go from 0% to 14%
Expected: 28%
Actual: 32%
Discrepency: 4% additional heat

On my cicada (12 DHS):
If I fire 1 ERLL I go from 0% to 9%
Expected for 2 ERLL: 18%
Actual: 24%
Discrepency: 6% additional heat
--map 2
If I fire 1 ERLL I go from 0% to 0~5%
Expected for 2 ERLL: 10%
Actual: 13~20%
Discepency: 3~10% additional heat
--map 3
If I fire 1 ERLL I go from 0% to 3%
Expect for 2 ERLL: 6%
Actual: 18~21%
Discpency: 12~18% additional heat

As you can see, this is pretty ridiculous. Ghost heat is said to start at 3 ERLL.
Out of interest, here was a run with that:
1 ERLL: 14%
2 ERLL 33%
3 ERLL: 62%

I think it may have something to do with the amount of heat being dissipated and generated during the beam duration. Two large lasers generate twice the heat over 1 second than a single laser, but the heat dissipation is the same. What happens if you instead chainfire two large lasers over two seconds to give the same relative amount of heat dissipation as one large would have gotten over one second?

What funky said. 3 is still the trigger even though I argue that it should be at 4 since medium lasers allow a maximum of 6 fired with the trigger at 7.

If you fire 1 twice, you will cool down to 0 in the same time as 2 being fired together, due to lasers generating heat over time, and dissipation starts the moment you have any heat. It's harder to see the more HS you have. There are heat simulators out there that are a great help for figuring this stuff out.

That makes sense; so it is like "number of lasers * heat per laser - heat dissipation" ... so in my instance something like
1 shot: 1*8.5 -2 = 6.5 heat
2 shot: 2*8.5 - 2" = 15 heat

So it looks like ghost heat ... but is just another hidden penalty. Yay.

Your examples appear to be working normally. Small discrepancies from the examples below are explained by ambient map temperatures.

Assumptions: heat neutral map, double heat sinks, 10 internal heatsinks + 2 external heatsinks, double basic efficiencies, 'mech standing still

Case 1
Firing 1x ER LL
Heat dissipation: (0.2 * 10 + 0.14 * 2) * 1.15 = 2.62 heat/sec
Heat capacity: (30 + 2 * 10 + 1.4 * 2) * 1.2 = 63.36 heat
Weapon heat generation: 8.5 over 1 sec
Peak heat value: 8.5 - 2.62 = 5.88 heat
Peak heat percent: 5.88 * 100 / 63.36 = 9.28%

Case 2
Firing 2x ER LL
Heat dissipation: (0.2 * 10 + 0.14 * 2) * 1.15 = 2.62 heat/sec
Heat capacity: (30 + 2 * 10 + 1.4 * 2) * 1.2 = 63.36 heat
Weapon heat generation: 8.5 * 2 = 17 over 1 sec
Peak heat value: 17 - 2.62 = 14.38 heat
Peak heat percent: 14.38 * 100 / 63.36 = 22.69%

Case 3
Firing 3x ER LL (i.e. Ghost Heat active)
Heat dissipation: (0.2 * 10 + 0.14 * 2) * 1.15 = 2.62 heat/sec
Heat capacity: (30 + 2 * 10 + 1.4 * 2) * 1.2 = 63.36 heat
Weapon heat generation: 8.5 * 3 + 4.28 = 29.78 over 1 sec
Peak heat value: 29.78 - 2.62 = 27.16 heat
Peak heat percent: 29.78 * 100 / 63.36 = 42.87%

It's actually not a penalty, if anything weapons with duration have the bonus of dissipation starting before all the heat is delivered, less of a spike. So if something instantly generates enough heat to shut you down, you will, where as a beam could have enough dissipated while shooting that you wouldn't.
