Hey Viggin, thanks for your feedback! Even though I'm not Josh, I'll share a few thoughts on what you wrote...
Please note that the stein<->tent pairings don't make the tents any easier to win... the steins just multiply the scoring of their associated tent. If you're looking to make tents easier to win, probably the best stein for that is Engler Pale Ale, which gives more time in all tents.
Also, I think you probably know this, but you don't need to win tents to progress in the game... winning tents is just about running up the score. Whether you win or lose the tents, Flipper Meister is the same distance away, as are most of the other fun mini-wizard features (except Duck Derby, which does get easier to reach if you win tents, since winning tents gives you extra ducks).
But certainly, if locations -- or home owners, especially since no one is playing much location pinball these days -- want to make it a little easier to win modes, that's totally cool... as you mention, it just takes a few seconds to pop into the adjustments and load the "Easy" or even "Extra Easy" presets, and don't even have to wait for the next code release. One good news/bad news thing about the American Pinball software update system is that normally, installing a code update does not change the machine's adjustments... this is mostly a good thing, because owners of games from other companies often complain about installing code updates: "I lost all my settings! I lost all my high scores!" That's not a problem with American's games... but it does mean that even if we changed the default (medium) settings in a future code release, an owner would still have to go install those settings... but everyone can do that already; whether it's labeled "Medium" or "Easy" doesn't matter much.
Hope this makes sense, and hope you have a blast playing the game with whatever settings make you happiest!
