M-type vs P-type Channels
Anthony Dougherty
Which is
right for me?
How do I
recalculate my
parameter?
What is this guy talking
about, would anyone notice
if I snuck out now?

Why are there two different types of Math?
The type “M” math channel was the original
averaging math channel in the ESC Data Controller.
M stands for Math Channel
The type “P”, average math channel was only
implemented with the introduction of the
40CFR75 program.
P stands for MathPack and is Average Math
3
Which is right for me?
P = P75
FID
M = P60
For KKKK “P” type math would be used
§60.4350(b)
§60.4345(b)
For Db most interpret it to be “M” type.
§60.48b(d)
§60.13(h)(2)
