From 7e83ef6fd00580ee20ef2305fd709b1f2048d6b2 Mon Sep 17 00:00:00 2001 From: Dave Evans Date: Fri, 25 Sep 2026 12:51:32 +0100 Subject: [PATCH] Update references to database refresh frequency I'm not sure how many of these claims are still accurate because I don't know how which of these data flows are still in operation. But I've updated them such that they're true on the assumption that the data is still flowing.
