Now, please stay with me and don't loose the plot as I go through some complex mathematics.
Well, sums actually.
I have 6 varieties of heritage pea seed which I want to multiply up. I only have 10 of each of them. I reckon it would be possible to crop 2 generations in one year.
I'd only take one variety for this experiment, if I do it, for reasons that will become obvious later.
I could start 10 seed off in the greenhouse in February or earllier for example, in a trough that I can later move outside. Having done this as a seed guardian, I know a return of 60 fold is possible. Therefore 600 offspring could be obtained from the first sowing.
These could be dried off and a late sowing made. The 600 seed is sufficient for a 50 foot row, the offspring at 60 fold would yield 36000 seed with this latter total being sufficient for a 3,000 foot row of peas!
I know there are various stages at which the equations could and no doubt would go wrong, particulary the the later sowing which would have to be done in open ground at a riskier part of the year, but it would be interesting to see what could be done in just one season.
