Mark,
I will first respond to your question since you have taken the time to understand the fundamental knowledge.
You are correct, this constant can be variable for each person. While the Haldane constant (M) varies somewhat among people, it varies only over a fairly small range. Such differences are even smaller when you consider the range of CO concentrations from fires that can vary by five orders of magnitude. While the sensitivity of this variable can be significant when modeling very low CO concentrations for an extended period of time, it is not as significant in the context of fires where CO can be generated in very high concentrations and exposure times are relatively short.
