I currently believe that the reversal step should be taken to completion, but I cannot say for sure if some benefits could be achieved if the reversal step would be controlled somehow. I don't see any reason now why it should. At least it wouldn't be easy. Just expose to bright room lighting at least for a minute or two, or take closer to your light source (fluorescent or tungsten), 30 seconds is probably sufficient at 20 cm (8") distance. But, it really needs quite a lot of light compared to normal exposure. 10-20 seconds of normal room light was not enough as I tested it.
