Daniel,
Your citation of Cuban cigar leaf designations is depressingly accurate. It is interesting to consider the possibilities. I question its applicability to home growing.
I would guess that most of the Cuban growers are not quite so arcane with their harvesting, and that much of the fine granularity of the grading occurs after the leaf is cured, based on size, texture and cured color. Traditional Turkish nomenclature divides the plant positions into as many named leaf grades. Somehow, the Turkish growers decided that each grouping consisted of three leaves, despite the easy observation that tobacco plant symmetry is in staggered pairs. In practice, both in Cuba and Asia Minor, the leaf is primed by its appearance, rather than by date, and is divided into many fewer grades for commercial designation.
It comes as no surprise that leaf characteristics vary in a continuum, from bottom to top. Even with only 4 position grades, I have found the variation from one plant of the same variety to the next plant renders categorical expectations less than predictive.
