'An improved procedure for combining Type A and Type B components of measurement uncertainty' looks promising.
Looks like the sump of exponentials is a hypoexponential distribution:

Finally! We are dealing with a hyperexponential distribution.

Got there in the end - we are dealing with a phase-type distribution
