PCC review | Golf Monthly

Whilst I appreciate that the calculation is somewhat of a secret, is there any way to see the scores that are put in to the PCC on a non competition day?
We had a medal on Sunday and PCC remained at zero.
No competition yesterday and PCC moved to -1....
Playing conditions, after all that's what is in the title, were as near as dammit identical, holes and tees weren't changed, just cut and rolled as they were on Sunday.
If they're going to have this sort of calculation then I wish they'd call it by it's proper name of Players Scoring Calculation because playing conditions seem to have naff all effect.
