Abort Rate Calc Question?

Just reviewed the formula for how to calculate an abort rate, (sorties aborted in air divided by sorties flown) plus (sorties aborted on ground divided by total sorties attempted). Total sorties attempted are all flown plus all ground aborts. My question is why is the abort rate calculated with sorties flown on the denominator on one part of the calculation and sorties attempted on the other? I would expect the abort rate to be air aborts plus ground aborts all divided by total sorties attempted, any insight?

Not Air Force (my Father was), but isn't an aircraft aborted in flight already sortied?

Not aviation, but I suspect any measure of mission performance would be useful enough to help narrow the abort cause in an effort to action improving it.

CPT Lawrence Cable it is. I guess I just don't understand why one piece of the equation would only be divided by sorties accomplished while the other is divided by all sorties attempted.

If you have 1 abort and 10 attempts, the equation is 1/10 to determine the percentage of aborts.
