don't know about everyone else, but when i'm doing the same workouts faster than i did them in a previous training cycle, i usually have quite a bit of confidence that i will race better then before. so isn't the goal the run fast in training, as it translates to faster racing? you can't introduce new stimuli without doing things faster than before...seems taking 1-2 months every training cycle just to shed pounds is a waste of time. look at Renato's posts on this, he is not a big believer in "down time/time off" as you start the next training cycle behind where you were instead of adding to what you've built.
I think you're just thinking about it differently, and using speed as a metric to judge your training. I will say that I am primarily a cyclist, and cyclists have other metrics to judge fitness besides speed (in fact, speed is an awful metric for cycling), so it is extremely common for riders to put on a little weight in the offseason, and then drop it before important races. This shouldn't be thought of as taking "down time/time off" because full training intensity can still take place in this time, it is only "time off" from dieting.
Optimal speed can be attained by dropping to a weight that is below optimal for the rebuilding of muscles that occurs during earlier phases of training. By cycling weight, you insure that your body has sufficient nutrients when trying to build, but can still achieve maximal speed at race time via weight loss.
If you base your training around times, this isn't going to work for you, but that's you, not weight-cycling.
