Ilan,
Per your request here is the VA with the leaning towers removed and the 90 day ramp up also removed. Discounting the leaning towers, there is a slight variation (generally<.1%) between the EA term in this report and the EA term in the reports the owners may have seen. This is because the owner reports are corrected for SCADA counter resets while this dataset is not. We are in the process of implementing a fix for this variation which includes storing the validated counter data in our database but that will not be complete before the AWEA meeting. If you show this data to owners at AWEA the folks from Trent may object as they will consider our availability should include leaning towers. By the same token the sites where we did not negotiate a 90 day ramp up may object as our availability should include the turbines from commissioning.

It only uses periods past the 90 day ramp up and removes leaning turbines. I have made one other change to the code. I discovered one case where the survey time was over 3000 hours, so I added code to remove all cases where the ST was greater than 1.10*Actual Survey. I have added a paragraph explaining these qualifiers.
