From a 25 cube session; up until ~20th solve, my session average was actually ~18.20, less than my best rollig average =P However, my last five solves weren't as good, so it fell to 18.40, with an SD of 1.75.
Also, my first solve of the session was 13.64, and OLL skip.

Edit: just realised something: that wasn't the scramble for the solve. After two solves, I accidently must have pressed the space bar twice at the start of the third solve, so I had to add them back in. Can you do strikethrough on this forum?
