For many months, I remember the platform RAR as below 10. From my records (I take a snapshot of my dashboard every month) the platform RAR was 9.98% at 31 May 2018 and had been dropping since then to as low as 9.72 at the end of 2018. Suddenly it is now above 10. Looking at the graph in Market Stats, the platform RAR (in the present graph) had stayed above 10% throughout. So the line had been moved up the last few days!! Occasionally, I also record down the Retail RAR and it seems the graph had been changed as well for the Retail RAR. Wonder what is the rationale for them tweaking it.
