Its on the list.
The instructions on how to tune a new way and the trumpets that have taken the test and it appears to work can be found on page one.
So far, 26 trumpets appear to lend themselves to this type of tuning. If you can, try out the test for yourself. If you are not sure what to do or if the instructions are not clear (which is totally possible) just let me know and I'll help you.
Tested it on the conn 40B but the ping on the bell is higher than the pitch with the tuning slide completly inserted.

Hey Dr. Mark, be sure to list the horns that do not work, or at least the total count. The percentage will be interesting to see, and may add to the information gathering.
Good point JNINWI, I'll add them up today.
I've quickly discovered that gathering the data and trying to interpret what people have found to be a major league pain in the ***!!
With that said, I've asked on of the moderators if they can put together a post where people can submit their own data.
I think some of the confusion comes from the instructions itself and for that, I'll take the blame, my bad. What I've done is to streamline the instructions in hopes that people will find them easier to understand which hopefully will result in better reporting.
Well well Dr. Mark, welcome to my world ! I look at trends, statistics, process control charts, histograms, and Statistical process control numbers all day…..so now you know why I asked for a bit more : )
Just don’t ask me to run an OC curve on this !! Thanks for all your hard work Mark, I’m sure this will pay off down the road !
To eliminate the human factor, BIAS (Brass Instrument Analysis System) could be used to establish resonant frequencies.
