Sala, while I agree with the other stuff you say, going 1600 to 2000km before lubing a chain certainly doesnt reflect my real world riding experience, certainly not with triflow.
On paved road trips I have done in the past, I have more or less lubed about every 5, 6, 7 days depending on rain and whatever, at perhaps 100km per day tops--but the nice thing with Triflow is that it isnt overly gloopy, and excess is easy to wipe off (even with a paper rag) in the day and days after a lubing.

again, respectfully, whatever works for you, but that seems a heck of a long time to go without some lube--perhaps on really clean roads (California) and no rain ever.

on the view of not lubing until you hear your chain squeak, I have the view that that is like drinking long after you have started to be thirsty. That more regular lubing, especially with inbetween thickness lubes like Triflow, means that stuff gets flushed out a bit by the new lube going onto each roller area, and it assures that the crucial area that needs proper lubing (the inside of each link) always has clean and sufficient lube there.

but then here we get into God vs Allah vs Buddha etc etc etc.......
