Where did you find this 5-3-1 variation? It's a little peculiar. 5-3-1 is a great program, but I seem to think you would greatly overachieve your programmed maxes on cycle. There is definitely a way around this I'm sure, but I would be more apt to use 5-3-1 off cycle as a means of maintaining strength. On cycle I am more of a fan of the West Side methods.
