The ideal plate should sit flush on the bone. You will notice the app automatically pushed the guide-plate out till it sits flush. If the plate is not sitting on the bone, screws placed can cause loss of position of the fracture, or the lag screws to cut out.
The ideal lag screws should pass through the far cortex by a couple of millimetres (bicortical fixation).
They should exit at 0 degrees to the bone (orthogonal).
Taking more X-rays exposes the patient (and the surgical team) to more radiation. But screw position is more important than an extra X-ray.
Swapping between 'AP' and 'Lat' views generally takes around 30 seconds, which will affect your time-score (also possibly contributes to increased infection risk.
Long operation times are associated with getting cold, increased blood loss, increased infection risk, increased anesthetic.
A faster operation, (but done well) is better than a slower operation, so you will get more points.
