Evermore and ever better correction

It turns out my probability radar was off, after all. Instead of just 2, I've actually had 6 evermore and ever better sessions:

date          delta  count

2012-07-17  -243000      3
2012-08-17   251150      4
2015-04-07    -5550      3
2015-12-04     2400      3
2015-12-08    95800      5
2015-12-09   -30000      3

Note that I only consider sessions where I played 3 or more sit and gos to be eligible. As the 2012-07-17 session vividly demonstrates, you can lose a ton of play money even when you're steadily improving throughout a session.
