Probabilty for 1 pair winning at showdown?

Limit Hold 'em .50/1.00

I am in the middle of an extended "no-swing", basically even for the last 20,000 hands. This has led me to look at some statitistics to see what has changed over the last 20,000 hands.What I have found is that 1 pair is winning about 7.5% less at showdown than normal. Here are my statistics for the year over a total of about 123,000 hands played:

103,000 hands
Average # of players saw flop 38.43%
% of 1 pair hands I took to SD 36.72
Hands won at SD 41.76%
Went to showdown with 1 pair 1 in every 41.5 hands dealt

20,639 hands
Average # of players saw flop 35.24%
% of 1 pair hands I took to SD 37.55
Hands won at SD 34.22%
Went to showdown with 1 pair 1 in every 42 hands dealt

Maybe this is standard deviation but one would think that if less players are seeing the flop & I am taking about the same percentage of 1 pair hands to showdown then the probabilty of them winning should be greater?

Breaking it down by groupings of about 20,000 hands

1/1/2005-4/15 ~ 1 in every 46 hands won 41.65%
4/16/2005-6/14 ~ 1 in every 36 hands won 41.34%
6/15/2005-8/7 ~ 1 in every 40 hands won 43.54%
8/8/2005-9/25 ~ 1 in every 44 hands won 42.64%
9/26/2005-11/10 ~ 1 in every 42 hands won 39.88%
11/11/2005-12/11 ~ 1 in every 42 hand won 34.78% (over last 22,365 hands)

Am I wrong in thinking that as the number of players seeing the flop decreases I should be winning more at SD with 1 pair? Or maybe I should be taking less 1 pair hands to SD becuase the pots are smaller? All in all this has me confused! any insight is appreciated.

You don't need to force the connection of how many players see the flop compared to how often you win at SD with a pair. In a 20k hand sample, it could simply be that you're running badly. You could see 40% VPIP or 15% and have your 1 pair win the same as you have.
