What shall be the recommended rate, for sending reverse sync in gptp Recovered Clock Quality Testing?

[MNaveen9229]

In "Recovered Clock Quality Testing" for AVnu certification , we are considering implementation of Reverse sync method.

Currently we are considering of sending sync/followup notification after sending PathDelayRespFollowUp.

But in the documents, it has specified that the rate of reverse sync shall match with the sync notifications received from master.(approx: 95%) .

So will it be appropriate to send the reverse sync notification after receiving sync follow-up notification ?
(or) Reverse sync notifications shall be sent periodically using a timer implementation?

Also how to notify reverse sync with different domain?

Answers for this queries will help me alot it proceeding forward.
Thanks in advance.
