Initially my Star Wars needed to be calibrated each power cycle. However, I ultimately correlated it to having problematic NVRAM writes. Once I got my NVRAM working correctly, such as successfully writing using the stored energy in caps when the machine transitions of power on to power off, I no longer need to recal each power cycle.
Maybe I'm lucky --- I've certainly heard many people say it's normal to require recalibration on power cycles -- but I don't anymore.
Do you have a stock SW or one with a kit?
Some info about my SW exercise is on my website @ www.aaarpinball.com

Turn the game off. Turn the game back on, and after a short delay, the circuit board would automatically output the mins and maxes that it had stored (D/A converter). That'd mean it would have to temporarily block the actual pot values from going to the board.
