A route is always calculated; by placing the waypoints correctly and using a sufficient number of them, the route will match the planned route exactly—provided the correct map is used and the planner's settings align with those of the XT.

It really isn't that difficult....
Thank you. For some reason, many believe that route recalculation can somehow be "turned off" when a GPX is imported into the Garmin. You can control recalculations in off-route scenarios, but there is no way for the Garmin to initially accept the GPX and automatically store it as created. Using MRA 1.2 is the closest GPX format to accomplishing no recalculation on the Garmin side, but re-calculation still does take place.
