how could appliances affect the r1?
Usually, for an intact ring, appliances connected wouldn't affect the result by enough to matter. However, if the line is broken, the measurement could well be via two (or more) appliances, if left plugged in and switched on. Part of the neutral conductor would be 'bypassing' the break in the line conductor, using the appliances to bridge line to neutral. Given the measurement of 107ohms for r1, this seems quite possible.
So the path could be: line (part) - load 1 - neutral (part) - load 2 - line (part)
Obviously, the measurement value would depend on the resistances of the loads in circuit.
