Even documenting your weeds -- you are very thorough, Frank !!
Johnny's Selected Seeds has some really useful interactive tools on their website --

My favorites are the Succession Planting Calculator, the Fall Planting Calculator, and the Seed Starting Date Calculator. These are spreadsheets with a lot of the work already done, for those of us not so familiar with entering the formulas to make them work.
