The learning curve formula is Y = aX^b, where Y is the time for the Xth unit, a is the time for the first unit, X is the unit number, and b is the learning rate exponent. For an 85% learning rate, b = log(0.85)/log(2). Using this, the time for the 10th unit is calculated to be between 8.0 and 8.5 hours.
