Of course, it depends on terrain and personal preferences. As has been noted elsewhere, it takes more snow to cover the most interesting terrain. If you vote for terrain, "adequate" will often also be a bigger number.
Without terrain, you get to practice arcs on corduroy, because that's all the area might have. Without "adequate" snow, you might be practicing arcs on corduroy anyway, because the good stuff sucks so badly. If it's too easy and boring for you, leave a ski at the bottom. Spend the day on just one. See how that works out in the New and Entertaining department.
If two places have a 20" base, I'll tend to choose the easy one, because 20" just isn't enough for what I really like to ski, but I know that it's enough on a slope with good summer grooming to go with its good winter grooming. 20" might be useable at Kimberly or Panorama, but Whitewater won't even be open.
If two places have a 60" base, the formula gives a different result. 100", different again. Your choice will depend on the snow. What is "adequate?"
Balance, butterfly, balance.
