Those spacings are traditional not few consecutive years but more than centuries, also they're proofed with scientific researches so I don't see any benefit on discussing this issue with anybody here. But please do not forget that they were determined for particular varieties or regions in Turkey, not for other parts of the World.
Those days, without watering systems and tractors were in the past, tobacco farmers benefit every opportunity nowadays (but intentionally limited). Everybody (scientifically or experimentally) are agreed that Oriental tobacco cultivation shouldn't be as intensive as other types (i.e. Burley), it's contrary to its nature. Among all crops grown in Turkey the most "rude" cultivation is applied to Oriental tobaccos. In a country where huge farmers use automatic controlled harvesting (or other type of) machines (without a driver/satellite controlled systems), you be sure that any other farmer may reach the best facility or equipment. Photos are nothing for people that don't know what to see.
Do whatever you want. If you like the taste of the smaller leaves grow it that way and enjoy, if you like the taste of that big leaves grow them bigger and enjoy. It's just up to your palate. You may like your home grown leaf but it's not rational to compare it's "quality" with the professionally/commercially grown.
A lot of people grew Burley in this forum, when they compare it with the commercial one they may like it more (or not) but it's not reasonable to compare it. I can say my TN90 Burleys, two years ago, were better than the X companies leaves but this's only to me, not rational, when I look at the standarts of the Burley leaf my leaf may be the worst quality. Although I liked how my TN90s smoked I can't say it's a good quality, because it'd be nonsensical, only a subjective justice.
If you're not able to apply/know related standarts, testing techniques and expertness you can't say "my leaf is good quality", you can only say "I like it" and may describe the taste. I'm sorry but this is the view of science.
