Yes, 3mil..
20 mil is better, I guess.
30 mil = 0.03 inches
the difference is negative 5 and the difference between 30 and 25 is 5. Some people look at the difference as absolute value so we have |25-30|=|30-25|=5
The difference between 5 and 30 is 25. This is calculated by subtracting 5 from 30, which equals 25. In mathematical terms, the formula for finding the difference between two numbers is to subtract the smaller number from the larger number.
30 mil = 0.03 inches

Length of case is the main one.
The difference between 20 degrees and -30 degrees is 50 degrees. This is because you subtract the smaller value (-30) from the larger value (20) to find the difference. Mathematically, 20 - (-30) = 50.
