Is this Jump in Stdev/100 Possible in 1 hand?

[XChamp]

Over 20k hands at NL$200 6max my Stdev/100 has been between $150-$160. I played one hand today that bumped it up to $206/100. If I edit the hand out of my database my stdev/100 goes back to $160.

The hand in questions contains me losing $200. That's it. It's not like I lost a $1,800 hand or something ridiculous.

I am pretty sure it is a PT bug, but can someone comment on whether my strong feeling that a $45 jump in stdev/100 hands in a 20k hand database all because of one $200 loss is not correct?

No, it's not possible, it must be a bug.

This would only be true if you won an average of $12,777 per hand over the last 20,000 hands, or lost an average of $13,177. If the first is the case you've won over $250 million and can pay for your probability calculations. In the second you've lost even more than that and should quit Poker rather than worry about statistical details.
