This isn’t a super-precise measurement, but for what it’s worth, it looks like the pace of SCA heraldic registrations is continuing to recover from the Covid dip, as shown by the pace of O&A database entries added per calendar year.
(Years are LoAR dates, often six months after submission; orange dots are the years significantly affected by Covid; gray dot is an estimate for 2025 based on the first seven months of registrations.)
