Sheer guesswork like that doesn't often come good. Smoked salmon for lunch! (Left over from V day yesterday)
200pF for the probe still seems a bit high, unless it has an unusually long cable. Maybe 2m or more. The source of the 1n reading still remains a mystery but it now looks like a measurement artefact of some unknown kind.
It's probably experience that makes engineers sniff out fishy(!) measurements. Amie, you've already gained more than about 99.9% (another bit of guesswork) of people your age.
