I had a similar experience where I had one day to do the challenge. I believe because my stream went past midnight it counted this as 2 days that I streamed when I only streamed once over 6-7 hours total. As a result my community was surprised next stream the day after when the boost was gone and we were never able to complete the challenge. For reference, our total to meet was 210,000 points and we managed to complete over 75% of the challenge in one stream. I average about 80-100 viewers across a stream. This may help give an estimate for how many hours streamed may be needed based on community size. I understand this is a more complicated algorithm to go by, but being able to only get 1 shot at the boost if you happen to stream late is a pretty rough go.
