When adding additional canisters to a single thermia fracture, each additional canister added to the first increases the time to defend by 25 pts / 30 seconds, and the base amount of time is 3 minutes, or 180 seconds. Then wouldn't adding 3 additional canisters to make a 4-canister seal only take 4.5 minutes, not 5.5 minutes?

180 seconds base

30 seconds * 3 more canisters = 90 seconds more

180 + 90 = 270 seconds

270 seconds total ÷ 60 seconds/minute = 4.5 minutes. Or am I missing something?
