Just to add this that experienced MD's that have regulars that show up can and should design COF's that won't put them at a significant time disadvantage. Meaning, if you have a COF that requires the shooter to take a knee or go to prone during the COF you can design that position to be at the end of the COF. Or if that position is at the start or middle you can break the COF into multiple strings without taking anything away from the design or challenge of the COF.
