Why do cartridge manufacturers give a range for VTF?


My Sussurros'  manual says 1.8 - 2.2 grams. I know that Lyra, particularly the Delos has it rated at a very specific number. Just wondering, It would seem that the stated range would be very narrow.

Lyra Delos also has a VTF range; it's 1.7g - 1.8g with 1.75g being recommended. 
All that means is that they want you to start at 1.75g and move on from there. This is no different than any other manufacturer
