Calculates optimum barrel time. The picture tells it all.
New version, converted to html code.

Most certainly not trying to be a smart aleck, but what/how does this help in reloading? Serious question.

Linky now worky! Updated version as well!
Looks like this:
Updated version today. Will save all Nodes as a .txt file on your computer if you want to.
Silent upgrade today to v 1.1
Updated today to v 1.2. Updated some code to get it to work faster. New look on the save to txt function. Will show program version, store data (as before) and also show date and time when the file was created.

Silent upgrade to v 1.3
Updated to v 1.4
Changed some of the txt file layout.
It's the reflected pressure wave in the bore. Some propose that is what causes SEE effect in the barrel. It can be predicted with software but only testing gives the results. A more useful number is time-in-barrel and it's effect with recoil! Follow-through counts.
Whatever!
Updated today to v 1.5. New layout on the save to txt function. Added error function to prevent saving an empty txt file.

Silent upgrade to v 1.6
Thank you for doing this!
Thanks, mostly done for fun!
New update coming soon. I have added the function to set Node numbers into the program. You can use both negative and positive values.
Looks like this:
Here is the new update to v2.0. Changed the link so there will be no "problem" with PC's catching old html data stored locally.
For negative values use - in front of desired node.
