Trying to solve the conundrum of ring size vs segment size

Just a quick question to ask why in the generated plan below row rows 6 and 7 show the same segment edge length even though row 7 is clearly larger? Am I doing something wrong? I caught the error in time and made row 7 larger since I wanted the edge to flair out.

Do you have your File / Options / Numeric display set to "nearest 1/16th"? I suspect you do based on your summary sheet. The software is rounding the numbers to the nearest 1/16th. Change your Numberic display option to show a difference.

When I recreated your vessel in WTP and changed the display option to nearest 1/32 it shows a difference between row 6 and row 7
Row 6 SEL is 25/32
Row 7 SEL is 27/32.

I like to use empirical decimal inch and a digital caliper for measurements. Here is your vessel summary sheet using imperial decimal inch.

That was it! Thanks Mike...I was a chemist for 38 years. Decimal inches have no appeal to me :) I guess it shows I have to pay better attention to my output.

There is the metric option. :)
Over time I just found fractions to be a pain in the rear. One reason I went with the decimal.
I also tend to over build still. That is if I want a 6 inch ring I make it 6.125 or 6.25 and turn down to 6 inches.

Enjoy the planning and turning.

I stopped overbuilding my blanks. I find it more fun to get as close as I can to the final form. I save a lot of valuable timber that way.
