Four is much more likely - one in the spaghetti bowl block, one in the helix block, one in load/unload, and one either waiting in the brake run or waiting to launch.
Maybe a five if there’s separate load/unload. No idea if it does because I never ask clarifying questions when I hear anything about this (based on what I had heard, I thought the raptor chase was screen based in the second launch tunnel, so by now I’m assuming I didn’t understand that correctly in the moment).
