@User: There will be no "repeated" parasitics. The "lumped resistance" values have no correspondence in SPICE and so they are not output. They will show up in a .sim file because they are part of the sim file spec, but "extresist" only uses the sim file to determine where the nets and devices are; it does not use parasitic values from the sim file. The recommended lines I specified above shouldn't change the output, but they will reduce computation time a bit by preventing magic from running unnecessary calculations.
