No, this chart is just poorly made. When the original was posted I tried way too hard to make sense of it and I'm 99% sure that the axes are off; instead of the edges being labelled, it should be the corners of the triangle, so for example pest is the top corner. Then, picking a point in the triangle, your pest level is the distance from your point to the bottom of the triangle; same with the other two corners, it's based off distance to the opposite side. Another way to look at it is that instead of following the tick marks in the direction they point, follow them parallel to the side adjacent to the "0" mark.
If you follow what the chart looks like it says, then not only do the percentages add up to 150, but, for example, if you're 0% fem you're forced to be exactly 100% boy and 50% pest.
