We are off to a bad start. You are confusing the amount of time you spend on promoting and defending OPMS with the amount of time I have spent commenting on it, which can be usefully measured in a few mintues. And I am already starting to regret them.

If you have something useful to say about OPMS, please get on with it.

Don't worry about me or Robert. Just take your best guess at what might be generally interesting to this forum, formulate what you think constitutes a solution, and get on with it.

I have read all the OPMS I am going to read. However, for the sake of this exercise, I will answer whatever questions you put to me, and I hope that other correspondents to Math-Teach will do the same.

Let the exercise begin.

Shovel ready? What shovel ready?
