Hi Matt,
maybe the attached helps you, or someone else.
I guess the limitations are:
- The assumption that the extremes of output occur when all component values are at one end of their tolerance range (so each component is either at the high, or at the low end, not somewhere in the middle). This is mostly the case for linear circuit functions. If this assumption is certainly not true for your circuit, I guess you're better of with a MonteCarlo analysis.
- Tolerances are symmetric and relative (in %, rather than in absolute Ohms, Farads or what have you).
- Size of array supported by Mathcad (7 million at least).
- Calculation speed of your PC.
- Capability of modelling your circuit in mathematical formulae.
- Your imagination.
Success!

Added an _2k version, because mathcad 2000 handles symbolics slightly differently from 11.
