The horizontal axis shows the single numbers in the order of the wheel clockwise from Zero from left to right. Wheel: 0,32,15,19,4,21,2,25,17,34,6,27,13,36,11,30,8,23,10,5,24,16,33,1,20,14,31,9,22,18,29,7,28,12,35,3,26
The horizontal axis represents the kettle, starting at zero clockwise. [0, 1, 2, ...] represents the Roulette straight-ups [0,32,15,19,4,21,2,25,17,34,6,27,13,36,11,30,8,23,10,5,24,16,33,1,20,14,31,9,22,18,29,7,28,12,35,3,26]
The vertical Axis shows the conversion, the relative win / loss for every straight-up.
The black points show the straight-ups (as mentioned for horizontal Axis). The solid black line is only a connection of them.
The dark blue line shows the average in width 2-X-2 The light blue line shows the average in width 5-X-5, nearly 30 % of the wheel The green line shows the average in width 9-X-9, therefor 19 Numbers = 51.3 % of the wheel.
The pure mathematically rate of 1:36 is shown, the lower red dashed line represents the mathematical zero line. The upper red dashed line is at 2.7 % and shows the house edge.
what can you see
So what can you see in this illustration? The higher the black point is, the more "favorite" is (was) that straight-up. Everything around the 0 % line is a normal one. The numbers on the bottom are the laggards.
I don't know what one can exactly read out of this representation. I don't want to conclude any strategy.
The idea was to show the change of randomness at roulette and its physical correlation.
Maybe some people get an idea, why some strategies simply can't work.
