The manual calculations delay seem like a load of crap. Last time around they overpaid millions and within 5-7 days, knew exactly what each employee owed back. That was back when there was a dollar raise at your 90day mark. This time around it seems more cut and dry, but they obviously owe much more back this time around. What a crappy delay.
They could have just thrown something out there early on and fixed it like the last time around. I still sense they'll delay things and still have the pay be wrong.
