It’s important to be really honest about this, there are a whole range of different factors is play because items and authors are hugely different, and require different kinds of review. We prioritise based on value. We give priority to authors who have particular histories, Elite authors, and yes, sometimes to new authors. We also de-prioritise authors that have re-submitting the same item multiple times. This stems from a desire to improve the diversity of the marketplace and ensure our reviewers time is best spent.
