Table conditional formatting and Goal & Realisation practices

Hi, im having a table with 3 columns. Resource name, It's result goal and its result like below.

The idea i have is to color code PR% column in order to compare faster which result has reached its goal, but i did not manage to do that. Goal is a regular column, where PR% is a measure. So based on example we have Linia 8 with goal 66 and result 75.6 so id like to have 75.6 colored green etc. Am i able to do that?

Second thing is that if i show this in time like below: 

I'd like to avoid replicationg Goal column each month. Is there a way? On top of that id like to have same rule as above with color coding.

Also, if you guys have any experience or better practices to show such thing please share 🙂

Thanks in advance!
