Spatula said:F2/Mk6 attack bonus is +6/+1 for unarmed or normal attacks. Figure out what your unarmed attacks would be for your monk levels only (+4/+1 in this case) and replace the first to-hit with your BAB (+6 in this case). That is, you can use the monk's additional attacks instead of the additional attacks that you normally get for your BAB.
F2/Mk7: +7/+2 (BAB +7, monk +5/+2)
F2/Mk8: +8/+3 (BAB +8, monk +6/+3)
F2/Mk9: +8/+3 (BAB +8, monk +6/+3)
F2/Mk10: +9/+4/+1 (BAB +9, monk +7/+4/+1)
F2/Mk11: +10/+5/+2 (BAB +10, monk +8/+5/+2)
A very clear set of examples and explanation.
Now what if you flurry in each of those cases?
Thanks,
