Both reviewers recommend the paper be published, although a very minor issue (as described below by one of the reviewers) needs to be addressed upon its formal acceptanace.
"One mislabeling in the paper worth noting. For figure 8 they list rmsd and bais as the same thing, when in fact they are polar opposites. RMSD (or root mean square deviation) is essentially the rmse one the bias is removed. RMSE is the sqrt of bias^2 plus variance squared. Both rmse and rmsd are positive definite. If they want to show bias instead of rmsd (as I suggested) that is fine. Just relabel figure 8."
