What is initial contact resistance in relays?

Initial contact resistance is the resistance of the contact when the relay is new. As the relay ages, switching significant current, the contact resistance can be expected to increase.

I read "Performance (at initial value)"

I reckon it means at the beginning of its life cycle. In other words it may deteriorate over time. Given the state of the data sheet and the unclear definition of original manufacturer I would be looking for a more reputably sourced and documented part.
