bakers math

Is there a "standard" format for communicating a bread formula? If there is, I'd love it if some whould guide me to it.

I think Bakers' math is wonderful: a tool that carries so much information, in so few symbols. It's akin to tensor analysis. However, when I both read or write a bread formula I find myself stumbling. How do I "correctly" communicate the amount of preferment (sourdough starter, poolish, biga, pate fermente, etc.)? What useful information does the bakers' percentage of the total dough weight communicate? A check-sum digit?.
