Yes, I hadn't considered that. The DC resistance for the shorter length wire would, naturally be lower. I don't know enough about transformers to ascertain how much variance would be expected, but 30Ω represents a variance of approximately 7-8% which does not seem too unreasonable. That would seem to answer one question so thank you for that.
