Reporting every 3 degrees in the Brazilian Oceanic area?

[plans123]

Has anyone come across this?

I filed a plan reporting the standard 10 degrees in the Oceanic area whilst doing an ETOPS flight, but received a message from Brazilian Oceanic saying they wanted reporting points in the plan every 200Nms or 3 Degrees. The current AIP says its the standard 10 degrees...

Is this just Brazilian Oceanic being pedantic, or has there been a change to their procedures and if there has been, can anyone point me in the right direction of where it is written down?

Thanks
