Well - there is something funny about your first Rfree - it shouldnt be significantly lower than R? I suspect there is some muddle over the assignment of Rfree - one used for Phaser and a different value for REFMAC?
And of course at low resolution especiall Rfactors are very sensitive to scaling procedures..
