Its been said the Sigma 100-400 is not a quick lens for AF,one of the most difficult shots to get in BIF is the bird flying towards you, i think it did well here, if you look at the ISOs you can see it was not a good day for testing.
None should be missing, its the complete burst of shots, remember this is just an AF test no editing has been done.
