If SWL is 2,000 and the ER of the knot or splice is 50%, what is the RSWL?

When a knot or splice has an efficiency rating, the Reduced Safe Working Load is found by applying that efficiency to the line’s Safe Working Load. An efficiency of 50% means only half of the SWL can be used after tying the knot or splice. So, with an SWL of 2,000, you calculate 2,000 × 0.50 = 1,000. That makes the RSWL 1,000. The other numbers would come from assuming no reduction, a higher efficiency, or a different multiplier, which doesn’t fit the given 50% reduction.
