Roulette Spliter Hitter

This is a system which takes advantage of the trend on splits.
Every time a number appears you bet 1 unit in split with its closer neighbour on the wheel's layout.
For example 17 is the last number, 17 has 4 ways to split on the table,14,16,18 and 20, but only one of these numbers is closer on the wheel layout, which is 16.
So in this case you bet one chip on the split 16/17.
Let's say the second number is 23, 23 also has 4 ways to split with 20,26,22 and 24, from these four numbers 24 is the nearest on the wheel,thus you bet on split 23/24.
When one of your bets hits you add one unit on it, when a split doesn't come for 18 consecutive spins you remove 1 unit from it.
You continue to do so till you reach a certain session win/loss limit.
The principle behind this system is not only to take advantage of "hot" numbers, but also to gain from their neighbours.
In general I consider good idea to bet something which is happening more than its probability, in other words to go with the variance and not against it.
