yes, eventhough till yesterday, i was thinking that the ratio was 11/12 , now i think its 10/11 , cause a person i know was bnchmarking at 11x297 with 183 divider, and no way (even he, admitted that) he could have his BH-5 at 3266/12=271.... more probably its 3266/13 , so its 11*(11/10)=12,1 rounded o 13
