If you don't specify a start and stop, it does the whole thing.  By
using the "integral" measure along with "cross", you can specify by
characteristics of the waveform where to start and stop.

Probes do not do heavy calculations.  They just show what is there
inside already.  Also, probes do not influence the circuit.

A running integral would be a heavy calculation in this sense.  If you
need a running integral, one way to do it is to make a circuit.

Felix advise to try gnucap-adms would be good, except that it doesn't
work correctly.

But you can make a device to do things like this.  See d_meter.cc .
