CSS slider with autoplay more than 3 slides

Question

I want to add to this slider another slide:

codepen.io/miriamcc/pen/KzGGqZ

But I don't know how to calculate all settings in CSS, maybe someone have similar slider without JS or know how to increase slides number?

@EDIT

I fixed it myself: codepen.io/m17ek/pen/LYQyzbo

Here you go:

for future calculations when you add another slide :

duplicate this

/* add slide id here */
#slide4:checked ~ .images .images-inner {
/* increase this by 100% */
  margin-left: -300%;
}
/* add nth child after comma(,) near Color of bullets */ 
/* add nth child after comma(,) near Text of slides */ 

/* add this and replace 4 with child count and increase time after infinite by 4100ms   */
#play1:checked ~ div .fake-radio .radio-btn:nth-child(4) {
  animation: bullet 12300ms infinite 11300ms;   
}

/* do like above for this as well */
#play1:checked ~ .labels .label:nth-child(4) {
  animation: caption 12300ms infinite 11300ms;  
}

.image {
  width: 100%;
  height: 200px;
}
.radio {
  /*display: none;*/
}
.images {
  overflow: hidden;
  top: 0;
  bottom: 0;
  left: 0;
  right: 0;
  width: 100%;
}
.images-inner {
  width: 500%;
  transition: all 800ms cubic-bezier(0.770, 0.000, 0.175, 1.000);
  transition-timing-function: cubic-bezier(0.770, 0.000, 0.175, 1.000);
}
.image-slide {
  width: 20%;
  float: left;
}
.image-slide,
.fake-radio,
.radio-btn {
  transition: all 0.5s ease-out;
}
.fake-radio {
  float: right;
}




/* Move slides overflowed container */
#slide1:checked ~ .images .images-inner {
  margin-left: 0;
