Edited (not 50 base). 30 base scale + the number of heat sinks, both internal and external on top of that.
Many understand that pin point accuracy is one of the main issues with MWO weapons but on top of that is the heat scale and how PGI allows the heat scale cap to be increased by additional HS.

As expected, cool down for the DHS is 2x faster than SHS with the internal 10 heat sinks, as expected. If you take the SHS, it would appear the 100% heat scale is set at 40. The DHS heat scale appears to be set at around 50pts (base 30+ 20 more points).
Take 10 additional SHS would be at the 50pts mark while 10 additional DHS would be at 64pts mark (30pts base + 20pts additional internal DHS + 14pts from 10 external DHS).
So if PGI were to set the Heat scale at 30pts with NO increase in the cap, we would be looking at a higher scale the 10 SHS HS percentage after a mech fired 4 PPCs, as it would shut down as it would be at 32 heat.
Discuss why PGI does not wish to touch the Heat Scale, even if it was to remove the Cap extension?
