I also use Paterson tanks. Am I correct in assuming that the tank, when in the horizontal position, must be filled to the level of reel's center core. It seems to me that if I don't, then the film on the spiral near the core will not be adequately covered regardless of the rotation of the tank. If this is true the using a five reel Paterson to develop 1 roll would require much more solution than necessary.
