Indeed there is an element of truth in all this, and unfortunately it's very difficult to standardise voting with the current system (randomly assigned voters to submissions). If there is standardisation by having the same judges using clearly defined criteria, then there may be the very phenomenon we're all wishing to avert: a loss of the subjectiveness of artistic photography - submitters just looking to gain admission to PEG by simply meeting the 'assessment criteria' according to the 'rules' laid out by the standardisation.
You know, in the end, PEG is as presented - a gallery of images admitted by a democratic vote by imperfect volunteer judges (and who isn't?) that is only as good as the input provided by those judges.
And another example:
After a couple of different versions submitted with adjustments made according to suggestions - "This one doesn't look like it's going to get through - noise is the problem now"
I do see this and reserve to agree.
