Devices are working For single device, we’re seeing an average production increase of 35% over the milking cycle. Note that after week 19, Winter test is being compared to winter control. Average of weeks 1-19 is 23% increase, regardless of season.
 


Summer works well Only 19wks of data for summer, however one device yields avg. 21% increase; two yields 35%
 


…and winter works too One device yields an average of 19% increase in production; two yield an average of 11%. For the first nineteen weeks the average for both is 18%.
 Note: milk weight data for weeks 38-42 is suspect
 


The one device group consistently tested within a tight range, indicative of little structural variation between tests
 The two device group outperformed the single device group over time, averaging nearly 95lbs per week by Test 3
