When I hover the mouse cursor over some stat on the HUD, I often see two numbers in parenthesis like (5/10) meaning AFAIU that there were 10 opportunities to do something and 5 was done, i.e. the stat was calculated as (5/10) * 100.0 if it was a percentage figure.
However, on my custom stat I don't see this. I only see the end result, for example 50%.
What determines when PT3 HUD shows the (x/y) on the tooltip? Why doesn't it show the value at times? How does it know which numbers to show? Does it parse the formula somehow? Could I modify my stat somehow to enable the (x/y) values to be shown?
