Why are the edges in my conic-gradient not sharp? - css

Question

I'm trying to create a sort of pie chart using CSS conic-gradients. I want each the transitions between wedges to be hard, rather than soft.
In pie1, below, the transitions are hard, but adding an extra wedge (as in pie2), makes all of the transitions soft.
Could anyone tell me why? And how to avoid this?
(I'm using Chrome 80 btw).
.pie1 {
display: inline-block;
width: 100px;
height: 100px;
border-radius: 50%;
border: 1px solid black;
display: inline-block;
background: conic-gradient(
#FF6666 11%,
#FF8080 11%, #FF8080 15%,
rgba(255, 255, 255, 0) 15%, rgba(255, 255, 255, 0) 20%,
#FF9933 20%, #FF9933 27%,
#FFB366 27%, #FFB366 31%,
rgba(255, 255, 255, 0) 31%, rgba(255, 255, 255, 0) 35%,
#996600 35%, #996600 42%,
rgba(255, 255, 255, 0) 42%);
}
.pie2 {
