I did one more which gave me this:
1. 5 wraps with ends of the wire just in the postholes: 1.02 ohm
2. 5 wraps with coil in normal position, so with excess wire through postholes and not cut: 1.02 ohm
3. 5 wraps , coil in normal position and excess wire cut: 0.88 ohm
4. Same length, 6 wraps with coil in normal position, no excess cut: 1.35 ohm

My conclusion here is: same wraps, excess before or after the screws gives same resistance. Cut the wires after the screws and resistance drops. Add a wrap with initial lenght and resistance increases.
