I hope you were smiling when you typed that. I believe what we are both saying is that the geometric sequence won't work. I give. Divide a 33.3 unit line into 35 unequal parts decreasing in length from 1.18 to .88 is apparently just too hard.

How about these sizes: 1.18, 1.15, 1.123, 1.098, 1.075, 1.053, 1.034, 1.017, 1.001, 0.986, 0.973, 0.961, 0.95, 0.941, 0.932, 0.924, 0.917, 0.911, 0.906, 0.901, 0.897, 0.894, 0.891, 0.888, 0.886, 0.884, 0.883, 0.882, 0.881, 0.881, 0.88, 0.88, 0.88, 0.88, 0.88? I gave those to 3 decimal places, which is why the last five appear to be the same. An alternative to the way the list ends is to start with less than 1.18.

I now have a proverbial fish to eat tonight! Thank you. If you don't mind sharing the method (unless you did it by trial and error) I would be doubly grateful. If you do mind then I will eat my fish and be happily on my way.

My method wasn't good enough to be worth revealing, but I can give the values to 4 decimal places if you wish, which could be useful if you want to try tweaking them manually. Even when 4 decimal places are given, the smallest three values will still be the same.

Thanks but I'll be fine with 3 decimal places. If anyone else has a formula eating a hole in their pocket let me know. I will be designing more instruments in the future and this will be something I need to do each time. Thanks again.
