The hard lesson from dealing with the King of land based random number generators, like roulette, is that patience is a golden virtue.
The grinding wheel of Variance goes round and round, half of it under water. When we are going downwards, towards the water, we stop betting. When we leave the water, and are following it upwards, we start betting until we pass the top.
Round and round it goes, and with it, in a comfortable appose, we watch its highs and lows.
