So, I'm just running numbers and a few things seem difficult for me to understand:
Overwatch
So, every 15 minutes after performing an illegal action you get 1d6 (so 4d6 or a range of 4 Rabbit's Foot to 24 Albatross to get hours). That means you can be (out of 40 OS) online for between 10-1.6 hours after doing nothing else even if your target netted 0 hits. Next up, you have the actually doing stuff:
Scenario #1
Say every action is an illegal sleaze action, for 4 passes, and you're going up against the Seattle Metroplex Administration who roll Rabbit's Foot, average (1:3), or Albatross as Rating 7 with Firewall 9 (16).
For that combat turn, you've earned yourself:
Rabbit's Foot, everything glitches - 1-6 every 15 minutes
Average (5:16 * 4) 20 OS - so the most you can hold out for is 6 seconds (20 OS x2 Turns) before Convergence.
Albatross: Convergence in 3 passes (48 hits) ~2.75 seconds
Scenario #2
Every action is an illegal sleaze action, for 4 passes, and you're going up against the local Stuffer Shack who roll Rabbit's Foot, average (1:3), or Albatross as Rating 3 with Firewall 5 ( 8 ).
For that combat turn, you've earned yourself:
Rabbit's Foot, everything glitches - 1-6 every 15 minutes
Average (2:8 * 4) 8 OS - so the most you can hold out for is 15 seconds (8 OS x 5 Turns) before Convergence.
Albatross: Convergence in 5 passes (40 hits) ~4.5 seconds
My Conclusion
The reason I am asking this is because Overwatch seems to be out of the player's control as far as what they can do about it, in addition to the scale of time synchronising with meatspace runners. Technomancers can probably thread Cleaner (if the fading wasn't already really punishing). How do higher karma deckers/TMs deal with runs on higher level hosts? It seems at least 1 of your actions has to be the obligatory Mark, up to 3 depending on needs. Do you try to get more than mark to reduce rounds? How much edge do you end up burning? Is there a special piece of equipment you use? Do you run with more than 1 decker in your RL troupe? Do you have to go in with a band of NPCs? Do you get your non-decker buddies to log in with you?
