General Thoughts / Observations
Low-wind day. Fairly easy launch.
Nothing stands out as needing to change launch-wise.
Sticky should be 4 hours instead of 3.
By the time 3 hours elapsed, balloon was only around the low/high threshold of 19k.
I want to see float achieved (maybe around 23k ish).
Rise-time was so slow that it just took a long time.
