I always go to the STA International Tartan Index first when I need info on a tartan.
I just sent the SRT a query. I'll post the response or, at least, the thrust of it, though it may be a few days.

It would appear in general that the SRT is a work in progress. On their "Guidance" web page is the general statement, ...

"Where tartans have been incorporated from existing registers
The National Records of Scotland has worked with the Scottish Tartans Authority and the Scottish Tartans World Register to amalgamate their former databases into a single dataset for the Register.

It should be noted that the criteria for registration applied by these two individual organisations differed from each other and also from those applied by the official Register. Not all tartans recognised by one organisation were recognised by the other and vice versa. Notes or background information made available for pre-existing tartans may derive from a variety of external sources. Every effort is being made to check and validate this information, however it is acknowledged that inaccuracies or lack of clarity may still exist in some of the records. The National Records of Scotland will continue to work with its tartan industry partners over the coming years to improve this information."
