some of that luckiness is probably due the tree. what we need to do is breed a second generation of especially lucky stools from the same stock.
1. germinate new oak trees from genetic material recovered from lucky stool (1-20 years, say)
2. tend to trees as they mature (40 years)
3. fell trees, craft new generation of stools. (~1 year)
4. use stools until only a handful of lucky stools survive (500+ years)
5. iterate
if all goes to plan, by year 2600 or so the third crop can be underway
