I don't think there's any problem with this as long as you're not hurting the group (for example, clearing a turn before your group is done raiding on that turn for the week, which would instantly reduce loot to 1 chest if you cleared). In fact, I feel the people in the group should have been happy for the fact you're clearing.

They shouldn't be angry or shame you if they can't clear the content due to their own shortcomings, and likewise, you should not be denied your own progression - again, as long as you're not hurting the team in any tangible form.
