It appears that on the same day billing was enabled (Nov 7th), what
counted as a "Datastore Small Operation" also changed. Is that
true?

In all of my billing previews before Nov 7th, the count was at an
acceptable level, but started to climb on Nov 7th, topping out at
around 100x what it was previously. Causing an accumulation of over
$1,000 in bills that should have been less than a tenth of that. I
left for vacation expecting the billing preview level to stay the same
after billing was enabled, but appears that count() operations were
not included prior to the Nov 7th update?

Code wasn't changed since mid-October, and here are the counts for
small operations (in millions):
Nov 6th: 14 (Days before the 6th were at or under this level)
Nov 7th: 10
Nov 8th: 41
Nov 9th: 118
Nov 10th: 192
Nov 11th: 462
Nov 12th: 632

And then it levels out here, using up all quota each day, which was my
fault for leaving so high as I had imported a lot of data prior to
leaving. Code didn't change, traffic patterns didn't change (there
may have been a bit of a fight with spammers hammering the site a bit,
but that doesn't appear to be a totally new thing - still trying to
post-mortem that but very difficult weeks after the fact). Only my
bill went crazy.

All posts that talk about these operations changing reference these
two URLs:

http://code.google.com/appengine/docs/quotas.html#Resources
http://code.google.com/appengine/docs/kb/billing.html#operations_charged_for

One of which can't be found and the other doesn't seem to have any
information related to this.

Can someone clarify what changed and when?

The new pricing model has always included count() and our accounting code didn't change at launch. What is your app id so I can take a deeper look?

App ID has been sent via private reply, but for anyone else looking around it's "onlyrounder-sc". 

Thanks for taking a look.
