I do not know the answer to your questions but here is how my Retul fit was done.

1. First, ball of the foot over the pedal axle.
2. Seat height with slight bend in knee at bottom of pedal stroke and do not have less than 90 degrees bend at the knee at the top of the power stroke.
3. Move seat for and aft until the knee is over the pedal with the crank arm perpendicular to the floor.
4. Arms 90 degrees to the body with slight bend in elbows reaching for the hoods. Adjust stem accordingly.

Since you are an advanced cyclist, consider this. You want to have a light touch on the handle bars especially when climbing. You should feel like you could let go of the handlebars, steer the bike from your core and power up the hill. Having a longer stem is better for climbing while standing.
