That's probably true! We couldn't use Check-valve spouts in the study because one of the treatments used 1/4"-spouts, which weren't available at the time in the Check-valve format.
Strange long-term trend line. Statistically it really shows nothing with such a low number of data points. If you take 1999-2014 for example, suddenly the trend looks the exact opposite. This is why the number of data points makes it worthless.
@@abbyvandenberg5906 ok? The trend I was referring too was early in the presentation showing a trend towards maple season ending sooner as the years progressed. The data is misleading at best.
I think the graph you're referring to is actually of the date of sugar maple budbreak at PMRC from 1990-2014, which does show a trend, with interannual variation, toward an earlier occurrence since monitoring began.
@@abbyvandenberg5906 Yeah the graph @6:12, if you look at the points from 99'-14' (last 3/4 of the timeline available) the trendline would be completely reversed. Would be interesting to see this updated to 2022.
I don't see any comparisons with check valves--surely they would have shown a different picture.

@@abbyvandenberg5906 Interesting--never heard of 3/4" spouts.
Why would you use 3/4" and not "normal sizes?
@@4UncleRichards Quarter-inch (1/4"), not 3/4" 🙂

I'm not sure what trend line you're referring to, and generally I'm not much interested in responding to comments that include the word "worthless"

@@abbyvandenberg5906 and to clarify, my point has nothing to do with climate change which clearly is changing.
