You should start the engine, not keep wasting time spinning the pump. Once the rockers are in motion, the oil will distribute itself much more effectively than when they're sitting still, and it only takes a tiny trickle of oil to keep the rocker shaft lubed. The only purpose for the spit holes on top is to get a little oil to run down the rocker arms and keep the top of the valve stems wet when the engine is idling. At highway speed, there's plenty of splash inside the valve cover to accomplish that task.
