I am looking for feedback regarding betting variation based on the count in a DD game. I have read several different strategies. For example, one strategy starts with 2 units in a neutral count, dropping to 1 unit in negative counts, and going to 4 units in positive counts. Another uses a 1-5 spread with 1 unit in negative and neutral counts, and increases bets by 1 unit for every increase in the positive count up to a 5 unit bet. Another strategy doesn't increase the bet until a +2. Is one better than the others? Are there other strategies out there that are effective?
