The general control on QFP fine-pitch coplanarity is +3mils. suggest to look at the re-use of thrown out component from SMT machine. If the component pack in std pack, then most probably the lifted is due to processing, not incoming as the packaging

I dont claim to be a guru but I would say that the only cycle time you can control or be responsible for is your machine cycle time. Operator cycle time will vary and you cant control that.
