Service goals vs. user-defined goals

I was told once that there are internal goals that Flow Simulation uses to determine if a calculation has converged or not, and that these can't be controlled by the user. 

While messing around with the API, I came across "Service Goals" and think these may be those internal goals that I was told about. 

 

The following Service Goals were listed for a study:

 

dm/m

Calculate_inc time/NC_Fluid

Serv Press

Serv Temp

Serv Heatf

Serv Mflow

Serv MassFract0

Serv MassFract1

Serv MassFract2

Serv MassFract3

Serv MassFract4

 

Does anyone know if these are actually being used internally for convergence?  If so, is there any point to defining Global Goals for Pressure and Temperature?  What about volume fraction of each fluid component?  If the mass fraction of each is already being monitored, it seems redundant.
