Flex Take-Off Speed Bugs

The load sheet is complete and my T/O weight is 68T. I select the correct speed card and bug the speeds..but wait I may be able to Flex..Out come the performance tables for the runway in use and yes indeed I can Flex to 48 degees.

I notice that the VI VR V2 are all higher than the rated speeds as I would expect since I have reduced my thrust.

I have heard it said that you should only bug the flex V1 and the other speeds should be set from the rated speed card. I dont understand this and was hoping someone could explain the theory..

Thanks
