FORTUNE has collected professional and independent estimates of how many iPads were sold last quarter.
Among the professionals, the estimates range from low of 12.68 million iPads from Wedbush's Scott Sutherland to a high of 18.5 million from Cowan's Matthew Hoffman. The average estimate from this group is 15.07 million.
The average among the independents is 19.88 million -- 4.82 million (32%) higher than the pros and more than double the 9.25 million sold in the same quarter last year. The low estimate in this group was 17.7 million from Alexis Cabot, a American ex-pat living in Rome, and the high was the 24 million submitted by Asymco's Horace Dediu.
FORTUNE also looked at the six independent analysts with the best track record over the past seven quarters, their consensus is 18.6 million iPads, a year-over-year increase of 101.2%.
Apple's third quarter results conference call will take place on July 24, 2012.
