Discrepancy at Chesapeake, Israel, Waterloo?

I looked over the data from all of the regionals of the first 4 weeks after getting back from Chesapeake this weekend. At Chesapeake, there seemed to be an occasional problem where the middle blue alliance station would not establish communication with the robot. I was not surprised to see the data reflected this, with the Red alliance winning 61.5% of the qualification matches. I was surprised to see similar results at both the Israel and Waterloo regionals. Did you guys have a similar problem at your regionals?

Here is the data:
Code:
Regional                     Blue Win % Red Win % Difference 
Israel Regional	                37.97%	62.03%	12.03%
Chesapeake Regional	        38.46%	61.54%	11.54%
Waterloo Regional     	        61.36%	38.64%	11.36%
Pittsburgh Regional	        58.06%	41.94%	8.06%
Washington DC Regional	        42.11%	57.89%	7.89%
Finger Lakes Regional	        57.58%	42.42%	7.58%
NASA VCU Regional	        57.14%	42.86%	7.14%
Greater Kansas City Regional   56.94%	43.06%	6.94%
MI - Traverse City	        56.58%	43.42%	6.58%
Peachtree Regional	        56.34%	43.66%	6.34%
MI - Cass Tech	                56.25%	43.75%	6.25%
Philadelphia Regional	        56.25%	43.75%	6.25%
Wisconsin Regional	        54.93%	45.07%	4.93%
Midwest Regional	        45.07%	54.93%	4.93%
Bayou Regional	                45.61%	54.39%	4.39%
Los Angeles Regional	        54.29%	45.71%	4.29%
Oregon Regional	                53.97%	46.03%	3.97%
Boilermaker Regional	        53.85%	46.15%	3.85%
Arizona Regional	        46.97%	53.03%	3.03%
St. Louis Regional	        46.97%	53.03%	3.03%
Silicon Valley Regional	        47.62%	52.38%	2.38%
BAE Systems Regional	        52.38%	47.62%	2.38%
Oklahoma City Regional	        47.76%	52.24%	2.24%
New York City Regional	        48.05%	51.95%	1.95%
New Jersey Regional	        48.61%	51.39%	1.39%
MI - Detroit	                48.75%	51.25%	1.25%
MI - Kettering University	51.25%	48.75%	1.25%
MI - Lansing	                51.25%	48.75%	1.25%
Dallas Regional	                49.25%	50.75%	0.75%
Buckeye Regional	        50.63%	49.37%	0.63%
Boston Regional	                50.00%	50.00%	0.00%
San Diego Regional	        50.00%	50.00%	0.00%
Florida Regional	        50.00%	50.00%	0.00%
The difference column is merely how far off the results are from a 50/50 split (Obtained by abs(50 - Blue Win %)). You can see it jumps from 8% at Pittsburgh to 11% at Waterloo. Everything up to Pittsburgh seems to go up fairly linearly.
