Main, rod bearing and oil pump

Perhaps a score in the pressure regulating bore when performing the pump shim procedure Mr Hagg?
I watched Rawze's video of the oil pump shim procedure, the only thing I did different was I placed the dimes in the cup of the dogbone so they were "captured". I don't believe it should make a difference, but is there any possibility that if the dimes are on the ball end of the spring instead that they may flutter during startup and catch on something until sufficient pressure (80psi) forces them into alignment? Just spitballing
