Quoted from VALIS666:
Interesting. You have the numbers, but anecdotally the worst flipper fade I've seen on any of the modern machines was Stranger Things, and by a good distance. That left ramp is damn hard to make after just 20 minutes of play. Well, early Houdinis are the worst, but that was a known power supply issue.
Stranger Things, and AIQ. AIQ was also terrible, all of the ramps became next to impossible to hit from trap players before I added PinMonk fans. I don't think it's coincidence that AIQ's lower flippers are set to max, or almost max, power by default.
The little I've been able to see Godzilla settings, the flipper power setting defaults are much lower, so that might explain why there isn't as bad of an issue outside of the magnet heat and code adjustments from Stern.
