If you take Rips advice intermediates don't really peak for a meet. You just set up your numbers based on what you are capable of on your heavy day. It might be a benefit to take a light week the week before the meet but otherwise the intermediate phase is basically a phase of developmental strength. Really only maybe late intermediates and advance lifters actually need to peak for a meet.
The medium day is treated the same way the whole way through because its not actually adding to the stress on that day rather it is there to have a day in there to prevent detraining. This is contrary to the Texas method though.
