The bunched choke is the one that has a Fmax/Fmin frequency ratio of 6.
A certain amount of mental gymnastics allowed you to claim that 1.5, 2.1
and 2.7 are all approximately equal to 2... so how about 6?

It is a known fact that the VF of these chokes changes
with frequency so they don't behave exactly like a
transmission line. Bunching probably changes the VF
considerably more than a helical wound choke since
the first turn and last turn may be on top of each
other.
