Jim is right, mmikke.; consecutive break lines that go in opposite directions cancel each other like positive numbers and negative ones, to the extent that they are of equal value. In your example, the end break value will dictate a flag displacement on the right, high side of the hole, and amount to the dominating leftward break value minus the lesser rightward break value. Clearly, this is a difficult putt, as the break you are dealing with is a product of two opposite and extremely sharp breaks. The 3 second white dot falls between the 4 and 5 numerical values, and compound the difficulty. If you get close enough to the hole for a tap in, short of sinking the putt (which would warrant a public replay :-), you will have done quite well.
Should you encounter a like putt, with a beast of a downward slant to boot, my advice is call your mother for comfort, lol.
