The best way around this is to provide us with a copy of raw output from the developer's console (ctrl + shift + i) element viewer and store it in code </> blocks for us to look at.

Given how you've presented it means there could be different types of formatting that needs to be "filtered" out in order to retrieve the correct variables you are looking for.
Assuming that the variables you have are exactly as we see them, here's the regex to get you started:
(1:\s(\d+\.\d+))
Just replace 1: with 2: and so on

Let me know how you get on
