Burgundy:
In one particular case where I wrote about a belt whipping, several comments were like "OMG that's way over the top abusive!" and others said "Meh, he deserved worse than those little pats, that whiny brat" (I'm lookin' at you, CK...). So was it mild, moderate, severe? I dunno anymore! In my own opinion it was severe, but apparently not to everyone.
Ahhhh well, cyber-cousin, I'll point out that...
[1] My comments on your story "The Exception" were about each part in turn, thus when the male protagonist's discipline did indeed finally turn pretty severe in Part #5, I described it as being such in my commentary--when it struck me as rather mild, in Parts #2 & 4, I stated that in my comments following those specific parts. (Overall I'd consider the student's spanking to have been suitably severe, which I'll mention once I post my commentary on Part #6--sorry I haven't done so yet.)
[2] My analysis of the severity of the young man's corporal correction closely paralleled that of his female disciplinarian in the story, during Parts #2 & 4 she remarked that thus far he had been given quite a moderate punishment, then in Part #5 she seriously 'ratcheted it up' just as she'd stated she intended to. (I'm figuring that she was merely toying with her victim psychologically during the earlier relatively 'soft' parts of his chastisement.)
I'll agree that a spanking's relative level of severity is to a great degree dependent on how suited its recipient is to undergo such a tanning, both physically and psychologically. (In the case of "The Exception," the spankee was a collegiate athlete yet he had only been spanked infrequently and mildly during his young childhood, so possibly his spanker started out slowly to get him mentally reacquainted with the reality of being disciplined in that manner.)
The corporal corrections my characters receive are sometimes criticized as being "overly severe," although I generally have those strenuous spanking sessions undergone by characters who are both physically and psychologically capable of enduring them without any permanent negative effects.
"Describe the level of corrective severity which you're personally satisfied with, yet in general (unless such disparity is an element of the account's plotline) attempt to match that with the spanked character's ability to receive such corporal punishment."
That would be my suggestion to writers of spanking-oriented literature...
