HOA Deed Restrictions May Have Expired

My HOA was formed in 1986. The deed restrictions were formulated by the
original developer in 1972 and assigned to my HOA in 1986.The Marketable
Record Title Act requires deed restrictions to be 'of record' before 30
years expire by having the HOA Board file with the County Clerk,a notice
of preservation.
My Question: In this case,does the 30 year period start in 1972 or 1986?
The deed restrictions have a Notary stamp dated in 1972. No other documents
are on file except for a few amendments that were added to the 1972 original
deed restrictions.

Thank you.It looks like 1972 is the year because there have been no changes
as far as I know.

You gotta love Florida. It is funny. My original deed denotes the book and page but every summer sequential deed just states that the property may be subject to covenants and restrictions. That is not enough to reimpose the restrictions. It would seem to me that the best way to avoid this confusion is to have every deed specify the book and page and then have the clearly defined expiration date right on it.
