Formula To Return Multiple Criteria Including Stretch Target

I'm struggling to come up with a formula that ill give me the following:

I have will have a row of data (cells A4:H4 on the attached example), in the respective cells below each value in row 4 I want formula that will give me a value of 10 if it sees 90% in the cell above reducing to a value of 0 if it sees 80% in the cell above. I think that there should be a relatively straightforward formulae for that, my problem is that I want to add a further criteria that says; if the value in row 4 increases above 90% and reaches 95% then I must return a value that is 10 for 90% but "stretches" to 12 for 95%. Anything below 80% should return a value of 0, and anything over 95% should return a value of 12.
