If that's true, it'll be much easier to figure out the hard gathering requirements.
I lean towards the tiered school of thought and it has generally worked for me.

Possible longshot, but there may be a way to formulaically interpolate the minimum gathering requirement based on the delta in the desynth percentages associated with fish with known gathering requirements. For example, compare the desynth % success (use a fixed desynth level) for a 383G Frilled Shark (i80) to a 348G Sylphsbane (i80). That said, if two i80 348G fish have different % success rates at the same desynth level, this theory is shot.
