Highlight cell if value is .3 higher than next highest value

Hi

So I am trying to apply conditional formatting to a matrix (based on a bunch of avg values) which I know how to do but I need help with the dax command to use. 

Basically what the title says, very easy to explain I basically want a cell highlighted if the max value is .3 higher than the second highest value. I'll provide a sample of what I am looking for.

person1	person2	person3	person4	person5
4.2	3.9	3.8	3.4	3.6
3.1	4.1	3.6	3.7	3.6
4	3.9	3.8	3.6	3.2

so the ones highlighted in orange are .3 higher than the 2nd highest value in its row and in the 3rd row nothing is highlighted because it isn't .3 higher.

Note that I unpivoted your sample data to make it usable.
