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.
