Numbers vary depending on the survey and most surveys only include maybe 1/3 of commercially managed hives, to start. Overwinter losses are probably around your number for the last several years but all-year losses are much higher. The USDA stated for 2013-2014, for example, higher summer losses than winter for the first time, for an annual total of 42.1% * Regardless of the exact number, my point is still valid in discussing your original question.
