Weapon Comparison Charts - Efficiency or Weight Investment for benchmark scenarios. Scenarios are based on the following assumption:
In a given time (for example, 20 seconds), a certain damage number must be achievable or exceeded (for example, 160 dmg), without the respective mech with such a weapon loadout overheating. Ammo must be sufficient to repeat such an engagement multiple times (for example 6). For the damage/weight efficiency ,the actual damage achieved (which may exceed the minimum sometimes) is calculated and divided by the weight spend on heat sinks, weapons and ammo.
If the weapon balance was perfect, I would expect this to be on a curve that goes down with the range of weapons, and with weapons that cannot deliver pin-point shots (missile clusters or shotgun ammunition) be higher, to create reasonable trade-offs between range and damage as well as precision and damage.
Something for Heavier Mechs
The targeted damage numbers require too much weight investment that it's likely to fit on a light or medium mech. I believe that it requires 3 AC/5 to achieve TET=20 sec, TED 240, TEC = 6, you won't fit this on any light or medium mech.
Something for Lighter Mechs
The damage figures here are doable with most weapons even on a light or medium platform.
Weight Figures
These are just the weight figures without comparing them to the total damage result. It gives you an idea of what's realistically possible to equip.

Note: Next patch may bring balance tweaks to PPCs, ER and Pulse Lasers and will require re-doing the graphs.
