Agreed, what can I do but thank you for making a point I would have
let rest, I agree that ORTF is thus defined and that ORFT is only that

wording for "any pair of cardioids on a short bar and with any
inclusiv angle".

???!!! XY is XY, and in no way vaguely similar to spaced omnis.

Probably why Peter typed "spaced cardioids".
