For each tracking, I have to roll an extended test (10, 1 ini pass)
for each weapon's commcode separatly.
I also have to jump from cell-phone tower to cell-phone tower to cover whole Seatle (my commlink only has a range of 4km max)
Given the size of Seatle today (369,2 kmē) and that a standart radio tower has a rang of 10km (for easier math, we take a square of size 20 x 20 km) and
assuming that Seatle has grown a little bit and since we actually have a circle instead of a square: visiting 3-4 cell-towers should be enough cover Seattle.
With Track 3 + Computer 4 + Cyberware 3 + fullVR 2 = 12, I can buy three hits, i.e. 4 inipasses per code and tower. Which results in 16 inipasses = 6 CT per code.
