Regardless, if you keep your region at 400 food every day of the year, rot doesn't matter. If you want to double just the season rot so you usually have about 20-30 days' worth of food and drop to 10 days during summer, when all production is fine, sure. Go ahead, so if you give that much buffer room (800 bushels to start with) and still want to compare the the measly stock of 400 without seasons, it's still just 2.6% increase due to rot, which is insignificant to say the least.
