How precise should I be with my impedance matching networks?
More precision is obviously better, but I have no reference frame to judge what would be an unusable deviation and what would be an unnoticeable difference from perfection. Tuning inductance down to the nearest 250nH or so seems unfeasible, and that alone can easily be 25% off from the target, which is huge. That's not even considering the parasitics, which are basically unknowable and seemingly non-negligible at these scales.
Basically, at what point can I throw my hands in the air and say "good enough" without feeling like I'm squandering the potential of the rest of my rig?
