Let me plan and check a schedule
Sometimes I would like to plan out which days I will do workouts, and check if that schedule will keep me above the yellow brick road every day. At the moment if your plan is something irregular like 3 workouts a week, it is not immediately obvious when/if you will fall below.

Like Dan, I have trouble planning more than one work-out ahead. But something related to Robert's idea would be useful to me: I often wonder how much I need to work out to have at least N days of safety buffer. For that, the "bare min" is not enough.
One solution is to do the math. Another is to enter the planned data points, see what happens to the road, then delete the data points. Neither solution is ideal.

@Robert, are you hoping for more than the "bare min" shown in the goal stats in the sidebar? Like you want to be able to actually say "if i work out on monday and then again on thursday, will that keep me on the yellow brick road?"
My own way of using Beeminder is pretty myopic: when does my next workout have to be? I'll worry about the rest later, or just try to build a safety buffer whenever I can. But if were that good at planning my future workouts I feel like I wouldn't need to beemind the workouts in the first place.
Interested to hear other perspectives on this.
