Thank you for a quick reply Dr and for taking the time to explain your research with all of us!!! I was just trying to figure out this whole replacement thing and the benefits of CV's. If the research shows a difference in sap yield between using old drops with new CV's and using new drops with new CV's well then I would question the effectiveness of the CV. If the CV does its job I would think the yield should be the same?

We did that for several years. The criticism from some folks was that if we kept the vacuum on all the time then the CV spout would not be effective and a regular spout replaced annually would yield the same results. That is definitely NOT the case. The CV spout still outperforms regular spouts under those conditions.Originally Posted by cur dog

Dr Tim is there a link that we can use to see the data results on the vac on off system. I find it very interesting to compare the data for days and to see the result.
Thanks Ben
Is it safe to assume that there would be still "no significant difference in the sap yields" if the same experiment were done the same way except for using CV1 instead of the CV2?

What do you do with the dropline after the season? Do you remove the spout?
No. The results presented are typically averaged for the season, which is the "norm". It is extremely rare (for almost any scientific experiments....not just these) that the entire data set is published. Generally results are analyzed and presented in some summarized form (graph or table)....typically to save space in whatever way it is being published.

I assume you mean with systems with a CV spout or adapter. There are several ways to do it. With a CV stubby and adapter you would either plug the adapter into the pin on the tee, or with a separate plug. With the CV2, you would either put it into a cup-tee, or cut the spout off the drop and plug the dropline into a tee or with a plug.

I was thinking of the CV2. Does the spout fit that tight that it has to be cut off?
They come off harder than you would think. I have one on my desk and I can not pull it off. Anyhow I think for better results next season cutting them is the way to go you don't want to stretch the line cutting is probably faster and yes the drop will get shorter. For this reason I started making all of my drops longer plus using the Data from Tapping Calculator DR. Perkins shared.

I do too many to be cutting them off. I would go with more of the CV1's but am worried about them being discontinued since there is a new one out.
