Sentencing Starting Points
A "starting point" for sentences are set as guides and are factors to consider the appropriate sentence. They are meant to achieve greater uniformity and consistency. They are "most useful in circumstances where there is a large disparity between sentences imposed". 
Generalized offences with a "myriad of factual underpinnings" have been rejected as having a fixed "starting point".
The "starting point" is an effective mid-point within the range of sentence for the offence. 
A starting point of sentence will be raised and lowered after considering the aggravating and mitigating factors on sentence.
A starting point cannot be artificially lowered by examination into prior case law that shows lower sentences than the designated "starting point" and deem it to be the "correct" starting point. 
A judge would does not mention starting points in sentence where one exists is not committing an error in principle.
Starting points assume the accused is of good character with no record.
