SRMs get significantly more effective per heat the larger the launcher. While this is good in theory, smaller launchers get further penalized because their more rapid cool down makes them run even hotter than the SRM6s. SRM4s also get hit with ghost heat.
3xSRM6 delivers 18 missiles--38.7 damage for the Inner Sphere and 36 damage for the Clans.
4xSRM4 delivers 16 missiles--34.4 damage for the Inner Sphere and 32 damage for the Clans.
3xSRM6 produces 12 heat and are unaffected by ghost heat.
4xSRM4 produces 13.2 heat (12 base heat + 1.2 heat scale penalty).
So SRM4s do less damage for the heat they produce than the SRM6s, even before accounting for ghost heat and the cool down.
The values need to be rescaled so that taking smaller launchers is a viable option.
