I have been doing this in my house. Takes much longer than a day. For example I installed 2 Dolby atmos systems, with pipes for HDMI, network, power as well as 9 speakers - took many days in total.
are hdmi cable durable? i have too many bad experience with faulty hdmi cables so i never think of doing this.
Having run a few to ultrasound machines, never have the plug coming out the wall, have a female plug on a wall plate at each end. That way a ruined plug can be fixed and a new wall plate added without redoing the drop.
