Independent calculations on both sides then crosschecking according to company SOP picked up finger troubles all the time since i've been using EFBs. On the RTOW charts subject, however things weren't so simple, if my memory serves me well: at a certain operator in my career, FOs were doing the calc. and both pilots bugging their relevant ASIs, CPT setting TO power based on the above mentioned calc. done by the FO only. Plenty of room for error...still got away with it and so did the operator well before and after my time spent there.
