Okay just tested it and it's pretty much what I said. If no bloons are in range, it tries to place spikes as early into the track as possible (this is garbage imo)
Then the moment bloons are in range, it tries to aim at the one furthest along the track. You have to keep in mind the vision of the tower, no bloons in its vision even if they are in the track means it will still shoot towards the earliest part of the track it can do.
