Participation restrictions:
4 Tokyo girls - not going
Kanon - not going
Akeno, Akane, Kit - on jobs
2 spare clairvoyants - on hunting duty
That's 8 vets that should not be expected to participate in the Tokyo action at all, and 2 that will only be going on rotation.
Aside from Serena and our elites, we were looking at:
Taya + vet
4 teleporters
1 liaison
6 barrier
2 healer
2 stealth
8 artillery (including Kaoru)
24 vets
However, we don't need them
all the time. We're only planning two, maybe three attack runs per day with Serena. The vet team would only be on standby when Serena is actually going in to fight a class 3, and we're really only looking at maybe 2 to 4 hours for 3 attack actions. Will call it 4 hours for extra slack. (30-60 minutes setup and finding target; 15 minute fights; 1 hour break between each one; break camp after the last one).
Basically, for the initial careful sweep period, the vet team is just on standby for about 1/2 of their daily time.
I would then expect another couple hours spent monitoring the area by the scout team, just to make sure everything is stable, before they return as well.
Hours 0-4 (1/2 time): All present (24 vets = 12.0 meguca)
Hours 4-6 (1/4 time): Scouts (4 vets = 1.0 meguca)
Hours 4-8 (1/2 time): Scouts (4 vets = 1.0 meguca), vets+evac (20 vets = 10.0 meguca)
There's also break days, where we try to let the demons settle down. Still need to monitor activity, but don't need to bring in the full teams unless things change drastically.
A more reasonable approach to the overall cost is just to say that this team is on standby at half time for the month, and can bring its collective power to bear when Serena is fighting, with strategies appropriate to the situation. The other half time, Serena is on break, and the vets can do whatever other things they need.
That means it would be 12.0 vet meguca (well, 11.5, since the liaison will be full time regardless) to allocate the above team resources. Possibly half time for a lot of the elites, as well, though Taya will spend more time keeping watch than most.
Because we're going to be doing this in mini-turns, it's very difficult to be sure of meguca allocation for the entire month, because we don't know exactly how things are going to play out. The above seems a reasonable approach for the plans.
@inverted_helix - can we use this method for defining our general meguca allocation? The number of hours spent on it per day will vary from day to day, but approximately half-time for the entire month seems reasonable.
I don't intend to pull in more than the above two dozen, though various individuals with the same powers are likely to cycle through to avoid over-exposure of Serena's aura.
