i dont understand why people are keep counting 23 hours .....
i heard its on the basis of the time cost of plowing, planting and harvesting.
Those only take you ONE MINUTE/tiles and you consider it ONE HOUR/tiles. and there is 1440 minutes per day. making the ratio into 1/1440 which is a very small time ratio that can be considered negligible or not sufficient. Calculation based on 23hours a day in farmville is a total error!
