It is definitely tricky and we'll provide documentation in time. For now we'll try to help you here!
When mapping to a different property, think about the input value and the output value. If you want the output value to be the setup pose value, you need to setup your ranges so that happens. Erika explained well but I'll try to simplify.
You want 365.57 to map to 1. Start with:
365.57 to ? -> 1 to ?
Next set the ? values to get the behavior you want.
That simple mapping puts 365.57 as the minimum value for the input side. Alternatively you could put it as the maximum:
? to 365.57 -> ? to 1
Again set the ? values to get the behavior you want.
A more complex mapping could be to have a range 100 below and 100 above 365.57:
265.57 to 465.57 -> ? to ?
Next we know 365.57 is in the center of the range and we want that to map to 1, so whatever the output range on the right is, 1 needs to be in the center. Say we want 0.5 below and 0.5 above:
265.57 to 465.57 -> 0.5 to 1.5
With this mapping 365.57 input gives 1 output, just like the minimum and maximum examples above, but with different ranges. As you can see, there are many possible solutions depending on your needs, which is why Match is unable to do it for you.
You can do similar to arrange 365.57 and 1 to be at say 30% instead of the center (50%), but it takes a little math. We can help with that if needed.
I hope that helps!
