We're regrettably just past our major research projects of the year for most students (our 9th and 10th grade students do projects linked to the History Day timeline and focus, which means they're done just before our spring break at the end of March), but I'm well familiar with both of the calculators.
However, I hadn't looked at either of them terribly recently: I am again impressed at the level of detail and information (and I really like the noted 'No Time' option on the teacher info: I think it has some great suggestions.)
We've already made a point of reminding teachers of these resources when they're relevant to a project, and will continue to do that. I do particularly like the teacher reminders in the RPC - the "Here's the point where you should have a rubric" or "Review student theses here" might be particularly helpful to new teachers, for example.
I can also see the benefits (with some adaptation) when creating a professional presentation. I've got a fairly good sense of how long different steps might take me - but a little reminder never hurts.
Some of the listed forms in the guide area don't entirely fit a private school setting (different labels/focus/internal requirements, for example) but others (including Doug Johnson's plaigarism materials) are, of course, both fantastic and relevant.
