+/- is standard deviation. Just one std dev. You should be within that range about 68% of the time.
95% is two std dev.
6.6% was for 45 points lower than expected for 52 boards. I probably should have made the calculation for partnership on 26 boards. Should be close to the same number.
Holding no cards How do you do calculation

Forgot that I had the distribution for points for a partnership.
The probability of the partnership having 45 points less than expected
was much less than I thought.
20 +/- 4.77 per board.
+/- 24.329 for 26 boards.
1.85 std dev for 45 points less than expected.
1.85 std dev is ~ 3%
The probability of both partners holding 'bad' cards was less than I expected.
