These gears with 2 added shims to the relief should be yielding higher cold start numbers. A contaminated relief should yield higher numbers.
Lower numbers can be contributed to excess bearing play, damaged gears, leaking oil pump housing, blocked oil pick up, relief collapsing due to really high initial pressures (somewhat unlikely)
Throw oil filters every 1k miles and open your old ones, these should give you better insight if you're wearing prematurely.
