Thanks

@6:41 MTBF = 1/FR only if FR is constant. If FR is a function of time, this is not true. Correct?

Although the failure rate FR, is often thought of as the probability that a failure occurs in a specified interval given no failure before time, it is not actually a probability because it can exceed 1. Erroneous expression of the failure rate in % could result in incorrect perception of the measure, especially if it would be measured from repairable systems and multiple systems with non-constant failure rates or different operation times. It can be defined with the aid of the reliability function, also called the survival function
