I figure consistency is as good a plan as any. I use the same old shutters all the time, so the slow speeds are built into my process, the same old uncalibrated meters, the same developer and dilution, and I develop with some temperature and agitation sloppiness built in so my results are targeted with a range, not to the furthest decimal place. Bullseyes are great, but like you I am content with hitting the board and adjusting my aim as I go.
But to be clear: I have great admiration for those who refine their processes and routinely test until they achieve the results they want. I have seen prints from nearly perfect negatives (a subjective term, I know) that blow me away. I know my work will never get there, but I have made peace with that fact.
