If there is time, the word "carefully" should be deleted. It has to be assumed that it was not done "hastily" or "poorly". Should the x-axis labels be predicted rather than calculated values? There are small editing matter e.g., et al. with a full stop and consistent spacing around < and > that could be seen to. The message is not very clear to me. Does this say that the model predicts acetate and butyrate quite well, but is not so good for propionate?
