I applaud your decidedly realistic grasp of the situation, unusual for a woman. A willingness to deal honestly with the facts of bodyfat and muscle earn you an award of some sort, that I'll get in the mail to you someday soon. It has been my experience that women progress exactly as men do, but at a slower rate. Adaptation is a trans-sex phenomenon, and we all progress in a linear fashion, testosterone or not. But in realizing the different rate of adaptation said hormones allow, you also realize that the small plates cannot wait even one more workout. These little jewels allow your progress to behave the same as a man's in terms of its linearity, instead of being stuck for 2-3 workouts as a matter of course. You can use 2" flat washers glued together to make up the plates you need inexpensively, so do this tomorrow.
