I agree with stinky , but how ever if the recipe does not have them or you are having troubles finding them , I looked at the molding and finish ph ( the 2 most critical points of the make ) in the chart and they seem to be close enough.
I have had a few recipes that looked so good to me that I just had to make them but they did not have ph markers so I had to look up a few recipes that did and get an estimate and them from there make it a few times and adjust .
