Minimalist Approach to Full Synchronization

The goal in this video is to complete the memory with full synchronization (i.e., remaining undetected) without killing, hiring, poisoning, etc. There's nothing but good old fashioned hiding in this video. I use the GPS to help improve situational awareness, and I studied the patrol routes so I would know what to expect. Just for giggles, I perform this mission while Notorious, although this only barely increases the difficulty. This mission is not difficult once you know what to do. Here are some tips:
1:10 Two sets of patrolling guards near the plaza may suddenly spawn as you approach. Proceed slowly so that you aren't caught off guard. Wait for the patrols to turn away before continuing.
2:47 Gentle push the senator into the corner so that patrolling guards won't see him in case they walk by.
3:30 On the GPS, the red dot for this patrol was under the icon for the herald, so I didn't see them at first.
3:59 Patrolling guards may pass overhead. Be sure to check before ordering the senator to follow.
4:44 I try to avoid the corrupt official coming around the corner.
4:56 Keep right as you approach the stairs, and order the senator to stay behind you (so that he keeps right as well).
5:26 Wait for the patrol to pass, and then make a sharp right turn around the base of the stairs. Order the senator to follow you when there is nobody on the stairs to interefere with his movements. He won't be detected as long as he keeps right as he goes down the stairs.
If the senator is attacked...
Don't panic. Just back away from the fight and eliminate the guards with your crossbow. Alternatively, you can discreetly kill 3 civilians so that you restart at the last checkpoint. Either way, you are not detected and can still complete the memory with full synchronization.
