I believe they are ahead of schedule with this assessment due to the fact that himr tested the tigerlynk ath-60 in the tucurui reservoir with great success so they already know this reservoir. Checkout the prototype in action on the tucurui reservoir here at around the 5 minute 10 second mark of the video. Actual footage.
