While the number isn’t official (Apple (s aapl) isn’t exactly free and easy with its sales figures), one analyst is saying that although its early yet to tell, it looks like the iPad is on track to break some pretty significant records in terms of order volume. Amateur Apple (s aapl) analyst Daniel Tello, who regularly outguesses the pros, is now saying that around 152,000 iPads have been pre-ordered in the first 72 hours of availability.
Tello’s approach involves extrapolating Apple web order numbers. This time around, he worked with Victor Castroll, a Valcent Financial Group analyst. Together, they surveyed a sample group and found 120 orders for 137 iPads over 58 hours beginning at 8:30 A.M. Friday morning.

From there, Tello applied a formula that subtracts non-iPad orders on Apple’s site and multiplies the resulting number by an average of 1.125 iPads per order. Finally, he added in 2,000 units for late-night hours during which time they had no data. In the end, the total arrived at was 152,000 ending at midnight on Sunday. The number doesn’t factor in iPads reserved for in-store pickup. Read More about Analyst Estimate: 150,000 iPads Pre-Ordered Already
