Formula to calculate values - range of quantities

This formula may be potentially simplified by removing the "and ranges" which also guards against edges cases.

For example, 1 year is 365 Days, so 0.01 year presents a 3.65 day window the initial formula which may produce unexpected results?

Consider this logic too!

If (
    [Years Employed] > 10.00, 20
    [Years Employed] >  8.00, 15,
    [Years Employed] >  3.00, 10,
    [Years Employed] >  0.75,  5,

    // Default
    0
)
