Are the Octanes corrected for certain grades?

For the grades in the ARA blender; E5 Eurobob, E10 Eurobob, E5 UK BOB, E10 UK BOB and EN228 95 Non-Oxy, the blender finds the cheapest solution that takes into account that testing of the Octanes on these grades is corrected by -0.2 for both RON and MON. We display in the Grade Info as 95.0 and 85.0 as this is standard industry terminology.
