Computing time in diffalg

Hi all, I'm currently using the diffalg package to eliminate unknown signals and use the known ones for diagnosis (fault detection). At the moment, I have generated a lot of smaller equation systems from the large one I'm trying to diagnose. However, I get a lot of equation systems (too many to solve all of them), some goes very quickly to solve, others take a loooong time (too long for my poor computer). My question is, is there a way to "rank" the equation systems so I can start with the ones that have the highest probability to solve (other than the obvious number of equations in them)?
