Let’s calculate it step by step for Torn.

1️⃣ How many hits in 1 hour

You hit every 4 minutes to keep the chain alive.

1 hour = 60 minutes

60 ÷ 4 = 15 hits

So you will make 15 attacks.

2️⃣ Energy used

Each attack costs 25 energy.

15 × 25 = 375 energy used

3️⃣ Energy recovered during that hour

Energy recovery:

5 energy every 15 minutes

In 1 hour:

60 ÷ 15 = 4 recoveries

4 × 5 = 20 energy recovered

4️⃣ Total energy needed at the start

Energy used − energy recovered

375 − 20 = 355 energy

✅ Final Answer

To chain watch for 1 hour hitting every 4 minutes, you need about:

👉 355 starting energy

Example

If you take 3 Xanax:

3 × 250 = 750 energy

You could chain watch for about 2 hours comfortably.

💡 Small trick good chain watchers use:
They usually hit around 3:30–3:50 minutes, not exactly 4 minutes, to avoid accidentally breaking the chain.
