Force RX configuration for C4-C5 incomplete quad.

I understand each quad (rider is C4-C5 incomplete, weak triceps) has different functionality, strength, and ability, but are there some generally accepted rules to configure a Force RX to get the best possible performance? I'm referring to crank height, seat distance to/from the cranks, recline position (more upright or more reclined?), body height (putting extra cushions under the seat to get the rider higher). Thank you.
