Hi jcl. Sorry if this is documented somewhere and I missed it. A rephrasing and a further clarification question:

- How was it determined that 4 is the number? Is it based on statistical evidence reported somewhere? Is it your "Rule of Thumb" based on experience? Some other derivation?

- How exact is the 4? I.e., today is 2022-09-27. Does that mean the Asset's history must start no later than 2018-09-27? Or does the partial 2022 not count and history should start no later than 2018-01-01? Or is it a rounding thing and History can start as late as 2019-01-01?

Thanks!
