scroll down to the heat penalty chart.

(SRMs have not been updated in this one)
all weapons within the same group have the exact same heat penalty.

Hmm... "if a player fires a LRM20, a LRM15, a LRM10 together, the numbers used to calculate heat values will be from the LRM20."
how is that possible now that the numbers are all the same.
LRM-20 2 2.8
LRM-15 2 2.8
LRM-10 2 2.8
Didn't paul say that they would only have the same penalty when linked?
They couldn't figure out a way to add linked penalties to work so they made them all the same
